My satellite receiver died and I'm not sure where to go from here. I have Dish Network. I also have an HDTV. I'm not sure that I am ready to make the jump to something like the 921 model that is coming out soon. I'm wondering if there are any decent satellite receivers under $150 that could get me by for a little longer until the HDTV receivers drop in price somewhat. Is there really much difference in quality in the receivers around $150 or less? Recommendations welcome!
