The RPTV is just fine. I like mine just fine. $999 for 811 and a HDTV, or at least $999 for HDTV plus $149, (or $99, or $199, depends on who you listen to, call Dish to find out for sure!) for the 811.
It all depends on what makes you happy, if HDTV in a box is ok then it will work. In the end you get what you pay for, but I personally think the 40" TV is great, RCA has had some problems of late, I've read at other places that 1 and 5 Thompson TV's will need a major service call. Which according to Consumer reports, thats the worse of all brands. But, ALL TV's, not just RCA have to be repaired from time to time, it really comes down to how lucky you are. (you just have a higher chance of it with RCA)
Of course, I don't know if Dish still offers it to current customers, you would have to call them to make sure. Back in Feb. when I ordered mine, there was nothing that said it was for current customers, but it was. So you will have to call.
In the end, if your not crazy about having the most expensive set, HDTV in a Box is a good way for you to get started in the world of HD.
