if the rest of the frame is solid and you can get it for like $1000 or less I'd buy it, that is if you are comfortable with frame welding. I repaired that exact same section on mine, though the rust wasn't quite as bad. Since I wanted to mount a hitch and keep the same rear frame shape I decided not to plate it and just spliced in a section of frame that I cut off a junked vehicle that wasn't rusty. I only did one side though as the rest of the frame is solid.
