I dont think for $600 you can be too picky when it comes to hdtv's...just try to find them when they are on sale.
Element 32" LCD HDTV ($500)
this is the one I have (got it on sale for $450) and I am impressed with it:
32" Dynex LCD ($599)
both of these have built in HD tuners, so you can connect an
anntenna and get free over-the-air HD broadcasts.
