I currently have a Dish 501, an LG LST-3510A HD Receiver, and a Sony 36" HDTV. With my current setup there is no way to record / time-shift HDTV. I'm looking for a relatively low cost way to do this (my wife says I can't spend more than $400). I've read here about problems with the program guide, but I can live with it even if it's only 2 days. I don't need the Dish HDTV channels, just the ones from my OTA antenna. So the fact that I will not get MPEG4 is not a concern. If my use is mainly for recording OTA HDTV, should I get a 921 off of eBay? It would cost about $290 with shipping.
