I don't feel that you were taken for a ride. I think the repair was made in a very professional manner and although expensive I'm sure it came with a lifetime guarantee that you will never have to test/use. That little piece could have been welded but there would have been two places (inside the hole) that could not have been welded due to physical limitations of the welding equipment, read new crack started in the repair. What he did was essentially build a new cap for that pin boss in place. It is refreshing to see that there are still some craftsmen out ther that take pride in making a repair and making it stronger than the original.
