Ive been using a Ryobi cordless drill for prolly 3 years now things a beast. It works great and has taken alot of hard drops and blows to the wall from me throwing it around. Its just starting to get a crack in the handle now from to many blows to the ground haha. The batts. last pretty damn long to and I just bought the new 18v + batts and its like a new more powerfull drill. Just my .02
I have 2 or 3 Harbor Freight cheapies floating around. For all of $14.99 it's hard to beat just buying another drill/flashlight kit instead of just the batteries alone. I mostly use them for screws - they do a good job on ones that would strip if I tried a regular hand-held screwdriver on. And if I lose it or it gets wrecked... not a big loss.
