3/5 live, what's the minimum you need to call here?

effective stacks are ~$800, table is loose passive, a ton of preflop limping with garbage, over calling, missing value bets, etc. villain is a standard bad live player. he plays like 30-40% of his hands and always limps, almost never raises preflop, and seems to have a talent for min raising. he does have some live experience and isn't totally retarded, but he's pretty close. he has built his stack from his $200 buyin by having an above average run of cards where he won a bunch at showdown. i've been playing a standard TAG live full ring game, been aggressive in late position and have stolen a bunch of limped pots preflop without much resistance. the game is very easy for the most part, and i rarely find myself in a difficult situation... this hand did have me thinking, i will post results later...what's the minimum we need to call here?
