That looks identical to this Leadshine item. 151414015351 Leadshine has a good reputation for stepper drivers. They also make a 120 VAC input stepper driver with 8+ amps of output. If you have the time to wait you can get some bargains directly from China suppliers. Dave On 1/15/2015

These drives are not made by Leadshine. I have never seen a real Leadshine badge engineered by someone else (but they might exist). These drives are made by a different manufacturer and not in the same league as a real Leadshine. I have compared them side by side, I'll take photo's one day.

It is not a clone, both drives are black and that' s about where the similarity ends. The Leadshine name carries such weight that nobody will rebadge it preferring to use the original name. These other drives are sold under many different brands and I don't know who the real manufacturer is. I
