JJ on flop with one over?

[cbloom]

$50 NL, ten players.
blinds $.25/.50

Three limpers.
I'm in the CO with JJ.
I raise to $3
All fold except second limper

Flop 32K rainbow
limper leads out 2/3 pot

What do I do ?

Folding here seems too weak in general, Villain could have any pair below J's, also hands like AQ.

If I don't want to fold, is it better to call and see what happens on the turn, or put in a raise here to see where I'm at?
