25nl I hit my set!

[kabouter]

Villain(unknown) on the button raises to $1

I've got a $30 stack he has $25

I call in the BB with pocket 2's

Flop comes Ac7c2d

pot is $2.10, I check he bets $1
I reraise to $4
He reraises to $9
I shove

Haven't played for a while now, and just want to see if this was ok at 25nl.
Sorry that I don't have a hand history, but pokertracker has some problems with party poker atm.
