Another rain jacket thread...

I'm having trouble finding a good rain jacket. I've been searching around, found a few things, but they all have extra little features claiming to add "for extra warmth." I don't need that at all, I'm in Florida. I need something light weight, breathable, thin, etc. I am 6'3" and thin; usually a Tall Large fits just fine for a sweater, shirt, etc.

Any stores, brands, etc. I should look at?
