These look like great motors from their spec's: 128 oz-in continous torque, peak 1316 oz-in, 284 watt power output and the special construction gives more advantages. small disadvantage: no encoder.
I might be able to buy 4 of these locally, probably cheap compared to EBAY "buy now" pricing but there are no bids on them...
So what's the catch, are these good and what is a decent price?
I already burned my fingers on 4 good looking steppers and don't want it twice.

Thanks for the advice.
