I am gonna go out on a limb here ( I know, big surprise) and say that you WON'T get a better deal on a HD/S2/ATSC receiver, not counting the PVR. I don't count the PVR because mine doesn't work.
I just bought another Diamond from a guy in Canada for 168.00, shipped, brand new. If I get it and it isn't new, its STILL a GREAT deal as long as it isn't DOA.
A Pansat 9200 with the proper S2 card WILL run you 500.00. And yes, it has blind scan, but it STILL won't BS S2 signals, there are reports of the tuner being flaky.
I'll take my Diamond for less than 200.00, and enjoy my S2/HD on the cheap, thanks. I still have a great blindscanner sitting right on top of it, my trusty Coolsat 5000.
