I think I can at least put out a top five. Obviously this is only people I've actually seen or heard of before, I'm sure there are tons of other hot guys who play poker that are unknown (to me).
In no particular order:
Tony Dunst (Bond18)
I feel like I should preface the last one by saying I don't like a lot of what he's done in poker, but from a strictly aesthetic standpoint, I find him attractive.
Gus Hansen doesn't crack my top five, and probably not my top ten either. I don't find him that hot, myself, but realize I'm in the minority on that one.
