I tend to find that the skin on my body tolerates most sunscreens pretty well. I usually use Garnier or Nivea (do you have these in the US?).
For my face I love La Roche Posay's range - I really don't think you can beat them for sensitive or irritated skin, at least in my experience. They recently brought out an SPF50 facial mist which you spray on - it's incredibly light, and handy if you're wearing makeup. They do also do a range of body sunscreens but they're quite a bit more expensive than the ones from drugstore brands, and as my skin copes okay with those I don't really feel the need to branch out. I'm interested to hear what others use too!
