Well I don't what you paid but the 2800 is no benchtop machine. It is very capable. The acme screws, supernuts and gear reduction system perform very well with high accuracy. Speed is not its strong suit though I have seen some direct drive conversions that worked well according to the builders. If you got a Dyna in good shape, you got a great machine and or start. This is not an x2/3, or a G0704, it is a high quality well designed piece of machinery. Cliff, the creator/ moderator of the yahoo group never received his though he paid for it. Making a legal claim has done nothing but waste more of his time and money most likely.
A lazy man does it twice.
