Anyone used the Hot Dish 90 and a SG2100 together? Any problems? I'm going to put the motor on my brothers Hot Dish which is currently a fixed dish. When I got the dish last fall, the guy I got it from, said he tried a SG2100 and maybe a DG380? but had trouble getting it to to track properly. This guy has done plenty of installs so I certainly don't want any issues when I try this. The dish looks fine to me. Not sure what problem with tracking he would've had....Any ideas? Thanks Blind
