Magic, they're only for some bench testing, so I'm not that worried about reliability. They'll only be getting connected to some small steppers and a max of 30V, so I'm not going to be pushing them hard.
Here is a link to see the different specs http://www.omc-stepperonline.com/TB6600_vs_TB6560.html I have the TB6560 in a laser and they work ok without problems. But the others are probably more robust.
