So for me the $30 dollars per Injector would be better spent towards buying new Injector Nozzles and having the Injectors rebuilt.

It has been about 4 years since I pulled any but Injectors at the local Yard where $5 each. The cost may have gone up since then but I doubt if it has gone up to $30 each.
