Wow, this is most cracks, stabs and pokes I've read in a while about the type 4 and the 912E!
No need for me to give my opinion, but nice to read everyone else's.
It does have value to folks like myself. Let us know when you are ready to part with it. Can definitely give it a good home. The prices go up and down so that too would vary depending on when you pull to sell. I'm pretty sure you'll be able to offset the Subbie upgrade by quite a bit if the prices of donor/swap motors are as low as I had heard.
Good luck with your project.
