The elusive 30" HDTV that fits

Why is this so hard? I have a beautiful Borkholder cherry wood entertainment center that I have no desire of replacing. The interior will fit a TV up to 29.5" wide. Right now I have a 27" tube TV in there that I bought off of Mercata, which tells you how long I've had it. I'm ready to make the step into the modern era with a 16:9 HDTV, but it's proving to be an over-constrained problem.

TV manufacturers appear to have a few magic dimensions they support for TVs. 32" is one of them, as is 26", 37" and 42". It seems the the narrowest TVs are just under their diagonal picture size. So a narrow 32" TV is just over 31" wide: too wide for my cabinet, but from this heuristic, a proportionally smaller 30" TV would be perfect.

Unfortunately, they don't appear to exist. There are a few 30" TVs out there, but they are either tube TVs which are wider. Or for some crazy reason, the 30" LCD TVs all seem to have their speakers mounted on the sides rather than below.

I know it can be done. There are 30" computer displays like the one from Dell where the width is only 22". But then I don't want to spend $1200 on a pixel-perfect TV. I guess I'll keep looking.
