Toshiba Regza LCD would be my choice - they are very cheap right now and far better than Vizio or LG IMHO. We sold about 10 of them for Patio setups this year because of price point, qaulity, and they perform great. Not ONE of them had problems outdoor all year long.
They are availible in 720P/1080i versions as well as 1080P.
If you want pricing let me know. If your local I will give you a great cash and carry price, or we can provide cables/brackets/install if you need a whole package deal.
