I have a few Craftsman tools, but they're basically ones I found in the street, or in the case of my Router, a gift from my Mother. I have never turned wrenches for a living as an adult, but I started working in a hot rod shop in 7th grade as a gofer. Then I worked in a gas station through high school and then worked in machine shops for a year or two after school. I worked on my own cars and motorcycles until finally being able to afford a new car with a warranty. One thing I learned is to buy quality and only cry once. Sure it's a little more expensive up front, but if you need the tool now, you'll probably need it again at some point. The points made above about the more precise fit on the fastner is very valid. Not just because of the mangling that cheaper tools do to your fastners, but it is in fact a safety issue. I'm sure plenty of folks here have had that cheap socket or wrench slip on a nut at the wrong time and end up with a split knuckle or worse as a result. It's downright painful and could result in a trip to the ER.
Another good thing about better quality tools is that if you ever really need to, and I mean really, really need to, you can sell tehm as they do retain some resale value.
When it comes to driver type tools (Sockets, wrenches, screwdrivers), I have almost exclusively Snap-On and Mac. Some of these tools I bought used in good condition at a considerable discount as the person was either retiring or making stupid decisions and thought selling his tools would be a good way to make ends meet (probably works once..

). When it comes to ratchets, there is really nothing like a snap on to me. Not only do they seem to work better than the Craftsman and Mac ratchets I've owned, because tehy were built for professional use, if they start to wear significantly, you can get a rebuild kit for them! Snap-On still has a lifetie warranty on their non power tools as well.
I've also bought both of my roll-away tool boxes used. One's a Craftsman stack and the other has two Snap-On top & middle boxes on a Craftsman bottom box. Here again it seems you get what you pay for. The Snap-On boxes are better built.
I started buying my tools in Jr. High like Sid Post, and while some of them were used, I have felt the bite of paying the Snap-On man top dollar for a new tool I had to have, but I don't regret it as those tools never let me down and some of them are now over 25 years old.
For corded power tools like saws I've always gotten good service from Black & Decker although I'll admit there's better out there. I like Makita cordless stuff, but DeWalt is certainly great stuff too.
For pliers and dikes I think Channel Lock makes great stuff. Here again I have some 20 year old tools that still work well.
Klein makes great electrical crimpers.
The tool quality issue has recently raised it's ugly head in a big way in my garage. I've decided to pursue my metal working past and try my hand at building a garage based home machine/hobby/knife shop. I already have lots of hand and portable power tools, but decided I wanted a mill, lathe and larger grinder. I located a good deal on a small Taiwanese made metal bench lathe and bench mill and added them to my tool collection. On my first few projects I kept feeling like I was having to work too hard and not getting satisfactory results. Then a bad (read expensive) thing happened. A friend who knew I had been looking for some used machines (but didn't know I'd bought the Taiwanese stuff) called and told me about a lathe I should go look at. I was already frustrated with my little lathe so I went along. A soon as I fired the machine up and twisted a few dials it was all over. Now I have to find homes for my existing machines as I've arranged to purchase the Hardinge lathe he directed me to and am in the hunt for a Bridgeport mill. These are both heavy American made iron and will do anything I could ever ask, and then be passed down to another generation of machinists and still do tight work. The lathe was built in 1929 and will still hold incredibly tight tolerances. It weighs nearly 1800lbs where the new Taiwanese lathe weighs around 400lbs. Both are specified to take a maximum woorkpiece of 9"x20" so it's not like one's really a lot larger, just way better built. Unfortunately I'd spent time in machine shops and knew what a real machine was capable of, and once I was re-introduced to a real machine, I couldn't live with the imports anymore. They'd probably be fine for anyone who was just getting into machining as a hobby, but had never worked in a real shop. Lucky for me (but bad for our country) so much manucafturing is moving to China and Singapore that I can now afford true industrial grade machines for my home shop where even ten years ago machines like these would have been unthinkably expensive for all but the wealthiest home shop owner(I don't fit that last description).
I realize that you're not setting up a machine shop and may never use your tools much, but my point is if you buy the best you can afford you'll likely be happier and safer in the long run.
Just my rambling opinion.
