Alternatives to Dynamixel ax12a motors?

Does anyone have experience working with Dynamixel ax12a motors? I’m having trouble using their arduino libraries. The only function I’ve been able to get working is the ax12a.setEndless. I read that the signal that they require is half duplex, so I’ve tried using a variety of chips/transceivers (thvd1452, thvd1410, and SN74LS241N) to no avail. Has anyone else had this problem? Are there good alternatives to the ax12a in terms of size and power output?
