If you have a Lowes nearby, check them out on Friday's and Saturdays. They have clearances there all the time. I got my laser guided saw for $25 one day.

It is GMC brand. Not exactly DeWalt quality, but it works wonderfully.
If you are really strapped for cash, hit up rummage sales for some cheap tools. I have gotten nice drills at rummage sales for $1. (One day, I dream of finding a pinball machine at some ladies garage sale...

I can dream, can't I?)
