I am a day away from taking the plunge into HI-DEF. Wasn't going to do it, but I was made a very good offer at a price I could not pass up. Basically, I am having a new dish put up tomorrow and I am buying someone's slightly used Panasonic receiver. It could be the TUHDS20 model. Thing that bothers me is that I have read really bad reviews about this receiver include slow channel changing, overheating and sudden reboots. Hopefully, it may be the newer TU-DST52 model, but I know very little about it. Would make me feel a lot better if anyone out here in HTF land has any experience with Panny receivers. Thanks in advance.
