Andre, Looks like you have gotten some good direction as to the source to get the TracStar 360. All the research that I have done points to the TracStar as being the most trouble free and easy to work on and operate (no hooking up laptops to it to troubleshoot). To clarify further on the HD vs SD, there currently is not a dome, in motion or otherwise that supports Direct TV HD. The only way to get DTV-HD is with a tilt up dish ie: motosat etc. much like are discussed in post #4 and #6. Dish network does have in motion HD and several in motion domes that support it. Since I have Direct TV I can't comment on Dish.
