Can't say if thats a good piece of gear - But the price is way better than the $299.99 in their catalog! With the coupon it looks like over 20% off.
Just a little piece of confusion to think about. Cheers - Jim

If you haven't yet - do a quick search on the site here. I remember a problem that one member had when considering doing a cnc on the system. Something about it not being cost effective to replace the threaded rod - to match to motors/controller or something. But if you can use it manuallaly - sounds like a player.
