Size matters, that's for sure, but all in all the Aquos line of LCD TVs from Sharp have been the best all around. The new 45" in particular is great because it is the first 1080p LCD of this size. For a lot less money, you can pick up their for about 2k. These televisions are bright, represent color well and have an overall crisp picture.
I only have experience with the larger Aquos sets, so anything under 26" may not have the same quality.
