360 without HDTV?

This has probably been asked many times, but is it worth it to get a 360 if I don't have an HDTV?   How do the games look on normal, 4:3 TV's?  All the screenshots and videos that get posted on gaming sites show the full HD quality, so it's hard to figure out how games like Oblivion would look on my crappy TV.   Anyone have advice?

I run my 360 on a standard TV, and it's good enough for me, but graphics have never been a big deal for me. It all depends on how much of a premium you put on apperance.

I play all my 360 games on a regulat tv and they look good enough, except for Dead Rising, that game is unplayable for me cause its so painfull to read all the text.

Every other game (i have almost all the high profile games) present no problem whatsoever. Although I would very much like to play my 360 on a HDTV eventually :P
