Also for a cheap dremel check Autozone if there is one around you. I got the one I used for $16. Its super cheap and works great. I have had it for about a year now and use it a couple times a week and it has held up great. Has about 7 or 8 speed adjustments on it also. Cant beat it for the price.

Edit: Here is the one I was talking aout. It lists for $19.99. Come with a case and assorment of bits.
