Bulldoger,
I gave up on the whole copy protection scare thing last week after worrying about it for over a year. If you can remember, I have posted several times on the topic in the past. I finally broke down and purchased a 10ht and boy I'm glad that I did. I also purchased a new Sony DVP-NS700P progressive scan DVD player to go with it. The picture looks so good after calibration that I would be very happy with it even if they cut off the HDTV, which I now doubt will ever happen. My personal opinion is that it will be several years before anyone flips the 5C switch and cuts off the analog. If they do I would expect Congress to very quickly put an end to it after their phones begin ringing off the hook.
One additional thing to consider is that even the RPTV's that are coming out this fall won't even be capable of receiving copy protected signals from cable because the TV's will be required to have a POD module installed. The POD modules won't be in this years models for sure. So, that means that those RPTV's will be just as worthless as my 10ht when it comes to 5C cable programming anyway. Read the Mits disclaimer in the "Promise" statement and it says that the tv's won't be able to receive scrambled programming.
If I were you I would purchase a 10ht as I did and start enjoying the show. My DISH 6000 setup should be here next week! I've seen HDTV many times on other 10ht's and can't wait to see it on mine. Also, take a pass on the Sanyo. It is only brighter than the 10ht. I saw a demo last week. It isn't worth the extra $$.
Good Luck!
Bryan
