There a good inexpensive knives, then there are bad ones. Then there are the ones that make you say "Holy Mother of Pearl, what was I thinking!"
I generally do not buy "inexpensive" knives as I can afford nicer ones. Most of my knives are between $75 and $150. I do have a Strider SnG, and a Brian Tighe, but otherwise my portfolio is on the low to medium end of the spectrum. It is a well known fact (if you will) around here that Gerber, S&W, Mtech, Schrade, etc make crappy knives currently. That is not to say that they are terrible, and for the uninformed/non-knife person they get the job done well enough. BUT, for those of us who are knife aficionados know that for the same price as those crappy brands listed above, you can get a good knife like a Spyderco/Byrd, Kershaw, CRKT, Cold Steel etc. That's how I found this place, doing research on knives before I bought.
I've noticed that a lot of the people on the forum are quite young and/or new to the knife world, and don't like being told that their knife is a piece of crap. If it gets the job done and you're happy, that is what is most important. In life, you have to grow some thick skin and ignore the haters/snobs etc. Remember, many of us are older, have full time jobs and can afford nicer things. In other words, try not to be so sensitive, and take peoples opinions with a grain of salt. Remember, its the interwebz, and some people just have a big e-penis they like to show everyone.
