I am considering building a CNC Router, however I was wondering on if anyone has cut aluminum on a home made machine and how it came out? I have been reading over at the RC forums and this one and I am really interested in building one but I don't like messing with wood. I hate everything about it from the smell to the mess and everything!

I only have around $1500-$2000 to build my cnc thanks to some unused school grant. Thats not including a PC since I have tons of parts I can scrunge up somewhere. So any suggestions or comments will be great to hear.
