Hi John! I'm personally not familiar with these guys. You may want to post a link. I know Dan Mauch, the proprietor of Camtronics, sells some nice powerful steppers. He's also got a nice enclosure kit designed for the Geckodrives. You may also take a peek at the HomeShopCNC site. I've run one of his 1200 oz-in steppers with a Gecko G-210 and it rocks.
