I've not personally used them (I opted for Kinco from Zapp), however at least a couple people on here have used the cheap Chinese servos without any problems.

Drive/Motor set can be had for under $300.
The main drawback is the drives are only powered via the 240VAC, so if they lose power, you lose position. Whereas the logic in the Kinco drives is powered via 24VDC, so you can cut the 240VAC (i.e. an estop) and all the encoder circuitry remains active.
