I had a 23" Cinema Display [briefly, before it was destroyed in a fire] and now I use a Samsung 213T 21.3" LCD [which cost TONS less than the CD].
W/ the caveat that I never compared the two side-by-side, to my eye the Samsung looks as good as the Apple, I don't miss the 1.7", and the $$ saved makes a BIG diff, IMO.
Re: watching TV on it, it's gonna require a specialized video card which will run into some $$.
You cannot simply connect it to a TV...
Parenthetically, in the last year I have gotten into finding certain TV shows available for d/l on the web, but even w/ broadband, it often takes forEVER for stuff to complete. It requires great perseverance and patience.
