I was in the same "boat" about wanting to use an LCD for a monitor. But, due to the higher resolution of a dedicated computer LCD vs a TV/LCD I opted for a Dell 24" Ultra Sharp W2408WFP to get the maximum capabilities out of my Mac Mini. Yes, the monitor is expensive, for me about $599 plus $45 shipping but included a 3 year warranty. However, unlike a traditional TV/LCD's resolution of approx. 1366 x 768 you will get the full 1900 x 1200 with the Dell 24" monitor (as with most other quality 22"-24" computer monitor's.
Now that is important if you are going to use this display hooked up to your Mac as a desktop, i.e. web browsing, various app's etc. The higher resolution will make the fonts and fine details of what you are looking at much clearer than what you are looking at with a TV/LCD. PLus, with a 32" LCD you will need to sit that bad boy a good 3 to 4 feet from your face in order to focus properly. However, if like many users of Mini's you will use it mainly as an entertainment hub for movies and itunes than I believe the TV/LCD such as the 32" Vizio (I have one in fact) would make for a better investment.
