One of our very knowledgeable members ( Krifartida ) is an expert on Jobo equipment, and has recently advertised as having a complete stainless steel reel set- up including mint tanks. Hopefully he has reels for both formats, although I believe only the 35mm reels were shown-not sure.... Check the listings for April 13th of this year, and enjoy!
Thanks for the info. I'm not sure if it would be smart to break up his set of reels and tanks though. I just found out that the Hewes reels are still available from Hewes.
