John, the one that I am using now is a UST model2214P 5amp. motor variable speed to 30,000rpm. It includes: circle cutter, plunge router base, flush trim base, straight edge guide, flex shaft, various cutting and grinding bits. I used this to inlet the action on the stock that I made, also use it to make grips. I don't know of any other place that sells them, but you might have a Big Lots in your area. Dremel tools are nice, but the last ones I looked at only had a .6amp motor you could touch the bit with your finger and stop it, not enough power.
