Hey Pete, I will second the motion, the Satwork 3688 is a great receiver. i have both the satrwork 3688 and the Fortec LIfetime Ultra. I love the USALS on the ultra, makes it so much easier to locate sats when first setting them up, and it scans a bit quicker than the satwork. BUT, the satwork really pulls in the channels much better. I had G-10 scanned with my satwork, with about 15 channels, the Fortec scan only produced about 6, i decided to reinstall my Satwork using the positioner help of the Fortec and now have 45!
wouldn't trade my satwork for another receiver at any price. Next incarnation should have AC-3 , USALS, to make it almost the perfect entry level system.
