Standard with a set? - Borgata 40/80

[tradingman123]

Saturday morning game at the Borgata. The game is good, plenty of action players though no one is really splashing around.

MP limps, MP+1 limps, I limp with 33, two others limp behind, button raises, BB calls, everyone else calls.

Flop is K/8/3 rainbow, BB checks, MP bets, MP+1 calls, I just call and so does everyone else. Initial raiser now raises, MP and MP+1 call, do you pop it up here or go for the ck raise on the turn?
