I finally scored a Craftsman 43174 , they're actually very readily available on Ebay lately but I was looking for the best deal and kind of only paying attention to the listing result emails from my watchlist items.
This one popped up for $15 and I kind of jumped the gun, because the other that popped up at the same time was $12 but had some rode rash on the head.
I paid $20 shipped, and after purchasing a " similar result " popped up for a NOS rebuild kit for it which I wound up buying for $12.82 shipped since the selector has little wear.
Then after buying the rebuild kit a " similar result " popped up for another 43174 which looked unused, $20 with free shipping
I could have just done a quick search and got the like new example for $20+ tax but since I didn't, I'm into this one for about $33
Oh well, I'll save the mechanism I pull out and maybe one of you guys will need it at some point. It doesn't look all that bad but I'll get a better idea when it arrives.
