I'm a longtime Dire*tv subscriber and I would like to upgrade to HD. I have a 3 year old, HD ready, Sony FD Trinitron WEGA KV-36XBR450 television. I have purchased an HD dish on Ebay. I'm not as knowlegeable about digital television as most of the posters here seem to be. I basically plug in and watch. I'm very confused after reading all the information contained here. I would like to buy a good receiver but don't won't to spend a ton of money. Can someone give me some good advice as to which models will work with my setup? Thanks
