how would you play it?

Mid-late sng, $150 blinds, 6 people in it (3 places pay).UTG ($2200ish)Button ($5k)Me($3k)dealt 79oUTG limps, button limps, sb folds, I check, ready to drop it as soon as possible.Flop 6TJ rainbow.check, check, check.Turn 8, 2 hearts on board now. I hit my straight and lead out with half pot size bet, $300. UTG raises to $900 (leaving him with about 1k), button folds.Now, this guy seemed pretty weak, I wouldn't put it past him to bet on a flush draw or top pair here. He'd called down some real weak hands and made terrible river bluffs on even worse hands. The only reason he wasn't out yet was a lot of luck on a couple hands where he caught big and got action.What would you do at this point? I reraised, putting him all in. With only $450 invested, was it good to risk another 1600 on a non nut straight? Seems obvious that I should do this, but kinda curious as to opinions in a situation like this, as it seems to be a leak in my game. Will post results tomorrow, though I'm sure you can see where this is going.

Yup, I put him all in. Sucks to be drawn out on, but you shouldn't be more cautious just because it happens.

Turns out he had Q9 spades and called of course. No help on the river and I was crippled, going out 2 hands later on a TT vs AK.Anyway, nobody thinks they could fold this after investing so little, even if you're pretty sure you're behind to the higher straight? This guy never raised except on the river a couple times as a bluff, so I was sure he was very strong when he raised me (standard calling station). It seems like I lose a lot of money on 2nd best straights running into top straights, so didn't know if I should ever just lay it down cheaply when I'm fairly sure I'm beat. At that point in the SNG, I could have easily made it to the money just playing premium hands and probably gotten 1st/2nd if I had folded.
