Paul!
With the resources available here (read - people, tribal knowledge of the 150/152, and so on), you shouldn't have any problem with finding a bird, even if it's not local (say, within a day's round-trip drive - 200 miles?).
Someone can and will stop by and look over the bird for you, maybe even get a chance to go through the logs and find out all sorts of things for you.
Sure, closer is better, but it's not a deal killer.
Good luck!!!
