I've had an Automach for about 25 years. It works well but is not very powerful. Also, the available chisels and gouges are kind of thin and easy to break if you pry hard while cutting. The Arbortech Power Chisel is powerful, but it's heavy and a bit awkward, and the cutting tool choices are limited. I also have a Foredom but have never tried the reciprocating handpiece. Hope this is helpful.
