I just did a colchester clausing lathe. with the centroid from ajax. Love the simple setup and programing (even I can understand it) and the guys know their beans. But try to get service afterwards. been trying to get help for 2 weeks now. one email response and that was to ask more questions, only got thru on the phone once and then was told there would be a updated version for download that afternoon. that was days ago. still nothing. so I dont think I would go the Ajax route again.
