a bricked PSP can be repaired. i think they install the modship with a firmware and then they can flash the psp again. later the remove the psp modship and all is done. but this is not cheap.
I hope it is cheaper than buying a new one... besides, as snkupo said: "bricks will _never_ happen if you care to READ the tutorials". So I think I will give it a try when I read more about it.
