Cost me $485. BUT- keep in mind I had to have my tank completely cut in half in order to weld the baffle back in place, that was major. The bonus was it allowed them to pound out the major dents while they had it apart.
They initially quoted me $200 to $250 without realizing the tank needed to be split. I wouldn't be surprised if you could find a radiator shop that would do it even cheaper. Just make sure the shop you choose is equipped to apply the sealer to the inside after they boil it out.
I am absolutely stoked with the results, I'll never have to deal with it again!
