Flop Top Pair, Weak Kicker from Blinds -- Bet Out?

[BruinEric]

This is a theoretical example, but I want some feedback on how you all play this flop.

Hero is in SB with Q [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img]
Six Players Limp
Hero Completes
BB Checks

Flop comes Q [img]/images/graemlins/club.gif[/img] 8 [img]/images/graemlins/spade.gif[/img] 2 [img]/images/graemlins/heart.gif[/img]
SB ???

In my newbie-SSH-land, here's my gut-reaction here:
I bet out because I have top pair and therefore good pot equity, which I hope to increase with some folds.

I also fold to 2 bets back at me, and consider folding to a re-raise by a good player. I possibly call 1 raise (to avoid "bet-fold to aggression stigma" and see what the turn brings.

What are your thoughts?
