Unless you need the full 10A from the DR8010 you can save over 200
bucks a drive if you go with the 80V 7A Gecko's. The 8010's are not
micro-stepping (the Gecko is) and that will definitely make a
difference in the smoothness of motion.

I don't think the guys at Microkinetics have figured out they are not
the only people building hobby priced drives and they have kept their
pricing intact using older technology while companies like Gecko,
Xylotex, HobbyCNC, Rutex and others have lapped them on price and
technology. This market has changed a LOT in last two years with low
cost stepper and servo drives, low cost CAD and CAM software and low
cost Controller software (MACH2, DeskCNC).

I have an older engraving machine I built three years ago (or was it
more?) that has DM4050 motor drivers but I jerked their ISA bused
Optistep card and their low feature DOS based engraving software out,
and upgraded to Master5 (later to MACH2). While I still use the
4050's, all my other machines built since then use Gecko or Rutex.

Hate to see you pay 345 bucks each for a motor driver when you can
get a Gecko for 114.00 and use the money you save to buy MACH2.
