32" is a safe size since it will definitely not use a TN panel, the max current size for TN panels are 28" so.
If you can sit within it's viewing cone the Samsung LN-32D550 comes highly recommended here for good blacks/contrast, overall image quality, performance and menu tweaking options. It is CCFL but the benefit of that is it will have even backpanel lighting compared to lower end edge-lit models.
If you want picture quality go with a CCFL lit LCD. I personally haven't see any low end LED's that don't suffer from blooming on bright scenes. Only full array LED's are worth considering if PQ is crucial IMO.
