I just got mine in the mail, too. It might be a little while before I can actually play, but I think it's going to be fun!
If I remember correctly, the Galaxy folks signed up here and answered some questions, and I think there was mention of possible Caffenol-based alternative for processing. Either way (waiting for an alternative or waiting to get the reversal kit), this is likely a summer project for me, after spring semester classes are finished.
I've got a homemade pinhole that takes 4x5, and I can also cut it down to use in a Baby Crown Graphic. Getting excited just thinking about it!
