I can't speak for or against the CM as I don't have one. I've read they are better???? I can't verify that, and I won't deny it. I do have a Fortec 1.2m dish and it works quite well for me. I use it with a Stab HH120 motor and it usually works good enough. It is very slow compared to the Stab HH90 motor, but it does handle the weight, most of the time. There are times (few) when I get aggravated with it, but I'm also impatient. I have actually gone outside to see if the thing is/has moved. A couple of times, I've even given it a little push. I've noticed, that this usually only occurs when it's been a while since the motor has been used. The more the motor warms up, the better it seems to go? Also, I try to remember to leave the dish parked uphill, when not in use, so it don't take so long to warm it up. For example, if I leave it on Hispasat (on my east horizon) or T7/IA7/G27 (on my west horizon), it may be a considerable amount of time before I can change to another satellite. Even the next one over (G10) by 6 degrees, it won't stop on it, without me giving it a push, or going to the next one over (Satmex5), and coming back to G10. When the motor is being used and warm, I don't have these type problems. I guess it's got arthritis or something, once you get the ole joints moving, it's fine.
