I dont know what crazy angles you lot view your tv's from but i have certainly never found viewing angles to be a problem on any of the RP sets ive had
Yes they are more limited than a DV CRT or a DV digital, but all the same as long as you put the set at the right height (its the vertical viewing angle which is more of an issue) then there will be almost no issue at all.
The issue is just the size, the image quality from a digital RP is going to be directly comparible to a DV of the same spec, i wouldnt worry about anything else.
