Thank you all!
I'm getting the rotozip for my b/f because he said he wants it and skipping the skil saw for now (my dad will probably buy it, my friend is moving to Oz and selling all her tools for $10 a pop). I'll just have to make the trip to the south bay, buy some wood and use my dad's table saw to make sure I get good straight cuts. I'm not that confident in my ability to do it with the skilsaw (yet).
The rack I am making is based on these ideas:

RioBravo's plans are good but I don't want to mess with the hollow core doors and filling them in, etc. I want something as easy as possible. I'm also playing around with the idea of using poly sheeting for the shelves (I can get poly direct from the manufacturer through my work). I'll come back and post pics in a few months once it's all done.
