I thought we had this discussion already?? Anyways, i'm going to say I use Ryobi. Like it or not, i have no problems with them, i have the Lithium batteries and they last a really long time now compared to the old yellow batteries. I use the impact for all my screwing, and it'll even take some spade bits when i'm too lazy to get the other drills for a hole or 2. We also have the 24v Ridgid sets which we use for drilling and cutting. I used to have bosch tools, and milwaukee, etc... but ya know what? They break just as easy as my ryobi, and cost a lot more! I also have the ryobi spiral cut saw, which in my opinion feels/works better then the original roto zip. And by the way, you really can feel a difference with the tools when you use the lithium batteries in place of the old nicad ones, they seem to be more powerful with them. Plus ryobi has a huge lineup of tools compared to others, where you'd have to buy all the different sets to get a new tool. We do however, mostly use our ridgid sets, for any large drilling. Only problem we have with the ridgid is if you're boring a hole or something, and it seems to take TOO much effort, the batteries basically 'shut down' and have to go back on the charger for a second to re-activate, which sucks.
