I'm also looking into which driver board to get. I finally finished my machine today with all the motors mounted to the machines, and all i need is the board.
I looked at those chinese boards and heard they needed alot of work to get them working properly.
I was originally looking at the HobbyCNC Pro driver boards that you have to solder together. Reviews say those are good, and members on this forum back it up, so i'm being drawn to this one.
A company that is local to me SOC-Robotics (Vancouver, BC) has boards based on the TB6560 chips for the same price that are already assembled, but i've heard some people have had similar problems with it as they've had with the chinese board you posted.
The gecko 540 is best i guess, but it is pretty pricey. I just checked the website and they are now $300 each when before they were $250; what's up with that?
Other than the Gecko for high price, or the HobbyCNC Pro for resonable price, what other boards are out there for us hobbyists for good prices with proper quality?
Thanks
EDIT: Just found this driver board for an okay price:
