Board and Motors package - opinions sought

Well it's a bit late to say don't even think about it, so here's a few links to help:

In short, they have their place - but a respectable CNC router is not it. The problem is the rated voltage of the TB6560 IC is too low to drive the motors often connected to them well - especially the ones in that kit. Here's why. If the motors in the link you've given are the correct torque rating for your machine, then you'd be far better off getting these motors as their inductance is lower, so they can be driven at a sensible voltage (75V) and get good performance. Look for individual drivers to match the motors - search on the forum and I expect you'll find more posts about this than words in this post.
