I have an SM-1100, I like it a lot. Although it's a small tv screen for my aging eyes, it's still good to have. I still prefer to set up my tv and receiver at the dish for fine tuning, mainly because of my eyes. I much prefer the Trimax for going on the roof for a tune up. It's just one piece of equipment and it stores in my tool bag quite easily, unlike the tv or receiver that has to take a couple of extra trips to get to the roof, not to mention dragging a drop cord up there. With the Trimax, not necessary. It has it's benefits, for sure. It would be nice if that screen was about 7" though? I guess you can't have everything?
