Does anyone have experience of the DMM Servo systems?

http://www.dmm-tech.com/

Some interesting bits here.

1. Accept step / direction input which allows them to be driven from something other than a CS Labs IP-A or similar.
2. Centroid / Acron now offer 'official' support for these drivers.
3. Good software, their vids on youtube are good, these dont come across as your typical chinglish manuals / software.
4. Pricing seems very reasonable.

Ive ordered Centroid Acorn for my lathe, I might consider a full upgrade to servos to further improve the machine.

Thoughts / comments?

Thanks
