Near the bubble, insane blinds

[Rooger]

$50 live tourney, 7 players left, 4 paid.
Blinds are 100/200 for the next 15 minutes, where it becomes 200/400. The total chip count is 6000.

I'm SB with around 600 after I paid SB. BB has about the same stack as me. 2 stacks with around 1200-1500, 3 at around 500.
Folded to me in SB with T[img]/images/graemlins/spade.gif[/img] 4[img]/images/graemlins/club.gif[/img]
The 2 remaining tables were just joined to final table, so I have no read on BB, and vice versa.

What is your action here? I'm average now, and might be able to sneak myself into the money. Though if I fold, I'll have 3xBB left, and even less FE with a push.
If I push, BB probably needs a good hand to call - but if he calls, there's a good chance I'm out.

Time to make a move, or fold and hope for a good hand within the next 5 hands?
