Anyone have any experience with Shangzhou Rattm Motor products? I was leaning toward buying Leadshine hybrid servos, but noticed these on eBay - http://tinyurl.com/zukuwsl

That looks to be a closed loop stepper, not a servo.
I bought two spindles from them and the quality control is suspect, but they were dirt cheap. I haven't used them yet.

Thanks for the comment. They are indeed closed loop stepper motors - generally designated as hybrid servos by the manufacturers.
