Bought a Dremel XPR400 set the other day for $20 on Craigslist the other day. The thing looks barely used, and comes with the handpiece and cable attachment. I figure I couldn't get burned too bad for $20, and I could use the bits for another tool if it burnt out.

I'll probably need to buy a collet assortment, but I definitely need some carving bits. I looked at Sears the other day, and they had some Dremel stuff, but didn't know if I could buy an assortment cheaper somewhere.

So what particular bits would you recommend for carving and where would you buy them?
