I bought the Badeco MX-1 Strong micromotor from Otto Frei a couple of months ago, and I have been thrilled with it. You can get 4 handpieces – regular (3/32), jacobs chuck style, hammer handpiece, and reciprocating (filing), so if you go that route it all adds up, but I’ve found it to be worth it. There’s a youtube video showing how it works. I also bought the set of Foredom anvil points, which work just fine in the Badeco and are less expensive than the Badeco ones. It was way more money than I wanted to spend, but I did not have good luck with cheaper micromotors, so I put it on a credit card and paid it off over a couple of months. The nicest thing about it is that you can adjust the force of the hammer strike by flipping a switch, which allows for a delicate tap tap tap for stone setting and controlled texturing in small areas. One thing I haven’t been able to find are videos for other creative uses (such as chasing and repousse), so I’ll just have to play with it to see where that takes me. Bottom line: I don’t know how I lived without it.
