Just got back from my local prop guy. I think his prices went up ($118 for 13", $130 for 14") but that includes anything that it needs. I showed him the photo from this thread and he said that price would get it back to as good as new even if it needed welding. He said that welding is just as good as the original castings and that he can perfectly grind/balance a welded prop, too. That is -- unless they are missing more than 50% of one blade, then he says they are junk. He has a pretty good pile of junk props that he just hangs on to until he can take them all for recycling at the same time.
I dropped off my 13" acme and my 14" stock prop. (Both have been repitched and welded by him before.)
I haven't priced out the other prop shop around here but at $118 I think he's probably getting close to what they charge (and welding is extra there... )
