$22, bottom two pair, call push on turn?

[this guy]

Don't have the hand history, but I remember it fairly well.

I've been playing very weak tight lately and am trying to work on that, but is this call a little too much?

Level 1 of a $22, stacks are all still roughly at starting size. I have 3s-4h in the BB. Two MP limpers, button calls, SB completes, I check.

Flop: Ks-3c-4s. I bet 75, folded to button who flat calls.

Turn: 10c. I bet 200, button pushes for ~700 (500 more), Hero calls.

In my short time playing SNGs, I've seen a fair number of people make moves like this with something like TP or a draw, but obviously at the same time I don't want to risk all my chips this early, if I fold I'll still have 500 which is enough to work with.
