Calling all-in with AK before the bubble in a €1 rebuy tourney

[danilaisback]

I rearly post here, but I had an interesting situation in a tourney. I am interested, what others think about the hand, what do they think is the best decision. THe situation is the following:

€1 (€1=$1.45) rebuy tourney at Paradise Poker, € 1000 Gar. 491 entrants, prize pool: €1237, 50 places paid (1st place:€309.25) average stack size:5363

We are down to 106 players, I have survived the rebuy period and have 7610 chips. The blinds are 100/200, no ante. Our table is 9 handed, Everyone folds to MP, who goes allin for 4570 chips, I am MP+1, and I have a tough decision now, call an allin with AK, and be in a very good position in case of winning and still have chips if I lose.
Average:5500, I have 7600.
Does it worth a call (I will be in a very good position), or should I wait for a better situation(I am above average)

I am waiting for the replies.
