Looking for opinions on motor performance between the top receivers. What is the most consistant, easy to setup receiver without compromising picture quality. Already have a SG2100. I have read comments online that some of the receivers just don't work reliably driving a motor setup. How do the PC cards compare driving a motor? So far haven't hit the magic combo to get my 102g to control the dish. For the cost of a higher power supply I can all most by a new receiver and setup 2 systems. Any opinions are welcome.
