[AMSAT-BB] Yaesu G5500DC problems?

I am contemplating buying a new Yaesu G5500DC rotor but have heard that the new DC motors were having problems. I wonder if there is anybody that has purchased the new DC rotors and what their comments are. I bought a new G350DC azimuth rotor and had to send it back twice for erratic needle movement. I would hate to pay $800 for a new G5500DC rotor and have the same problem.

Thanks for any info JACK KC7MG
