For $1200.00, I would get another frame. I see a lot of used frames with little to no rust for under $600.00. All you nedd to be able to do is transfer everything over.
My main point is, He is fixing the rot you see - what about all of it that you can't see? I fear that you spend all that money on a turd of a frame and end up replacing it anyway.
