I have the one made by ryobi. It was $48 with a case and 100 accessories at lowes when I got it. The dremel bits and everyhtng work well with it just make sure you get collets to fit the different bits(1/8"and 3/32").
Ryobi makes their own flex shaft to fit it, I think it was around $20 but I don't remember since I haven't bought one. I looked at everything there was and liked the ryobi best. The dremels are nice too, but the ryobi had more power(at least when I got it, the dremels might have been improved by now) and was a whole lot cheaper. It gives you 5 different speed settings between 8,000 and 28,000 rpm's.Check all the home improvement stores like Lowes, HQ, and Home Depot.
