Good suggestions here. I added a reciprocating saw, a level, a flashlight and some work lights to the list. I'd like to get a tool chest, but those things are $$$!

And thanks for the advice -- I think I'm going to stay away from cordless stuff. My drill is cordless, and I use it so rarely that the battery always seems to be dead when I pull it out. I'd rather just plug in and go and not have to worry about batteries.
