Can you even buy a SDTV now? I think even the small TVs I have seen in the stores are all flat LCD and I think even those will give you at least 720p. I know my&nbsp; LCD19" widesceen computer monitor is 720p.
It took me awhile to find them but you can get 13" TV's aimed at kids such as the "Barbie Bloom Tube" (CRT) or "Disney Cars" (LCD) that only do 480i. They do have ATSC tuners though. I doubt the folks with SD TVs in the family rooms are likely to replace them with these though.
