Looking for a smaller drill/driver around $100. Maybe a Bosch PS31-2A?

I got the Milwaukie deal from Home Depot and have been very pleased. My dad and I used the little impact driver to install a Reese hitch on my wife's car. Worked great.
 
Just got 2 sets in. The m18 and the m12 . I'm impressed by both sets. M12 is the hammer drill set.
 
I find the evolution of the cordless drills interesting in terms of using (my impressions). I started out with a 12v Porter Cable. I really liked it for around the house stuff. Started using it for work stuff and eventually dropped it off a 6 ft step ladder and it "failed" (ok, I broke it.) Black & Decker had purchased Porter Cable and I avoided buying this brand again. DeWalt seems to be B&D's better brand now. The replacement was a 12v Ryobi from Home Depot and I can't say I have been more pleased with the size, relative power, and convenience. As time passed and batteries improved to the Lithium batteries, you saw higher voltages with now stuff being offered for some tools in the 24v size. Lots of weight. You would have thought that with the emphasis on power being the norm that the 12v tools would have dissapeared completely, but they haven't. Things appear to be shaking out to 12-14v and 18v drills for the most part. I have all of these and just love the 12v drills for 90% of what I do. Have the 18v for higher power needs and corded for even higher power needs where portability is not a huge issue. My 20v DeWalt reciprocating saw is used a lot. I probably need to buy another battery for it as it only came with one... expensive.

Battery capacity (stored energy) is not the same as voltage. Power (torque) comes from more voltage or higher current levels in a given tool. Lighter loads will give you longer run times between charges.

There is no "free lunch", if you want longer run times for a given load or more torque, you need more battery capacity (i.e. stored energy) or higher voltage/current levels.

The overall jist of what you're saying is 100% correct. Good info. However, if I may nitpick here, power is not the same thing as torque. Torque is a force and power is the rate of change of energy. Mechanical power is the combination of torque and RPM together. But in the case of power drills, higher torque is more desirable than a fast top speed, so you often don't hear to much about it's speed characteristics.
 
Got to open the set today. I like the way it feels in my hand. But I have a question. Do I need special bits for use in the impact driver? I have seen "impact ready" sets but am wondering if they are the non impact sets given a black coat of paint.
