Paul,
Excellent news! I'm envious. I still love shooting with my Yashica 44. Mostly, though, I like the 4x4 format--it almost gets up to 6x6 in image quality but the cameras are very small, portable and unobtrusive. I use mine for street shots because nobody who looks at me thinks I'm taking a photo. (Unless they're over 50!)
I bought up a bunch of Efke 100 when I heard they were stopping it, and when B&H had a batch of that Rollei Crossbird stock I bought more than a little of that. Also, when Ilford did its weird-format run last year I bought 50 feet of Hp5 in 46mm. And I got a 100-foot roll of Portra NC a while ago on ebay. Also there's a guy in Canada who loads Portra on 127 spools and calls it 'Bluefire Murano'. You can buy that from The Frugal Photographer or from Blue Moon Camera, both in North America though. There are probably some European dealers too.
So I religiously save the backing papers and spools and I've done some spooling in a dark bag that (amazingly) worked well. I've got occasional access to a darkroom at work and am planning to load up a dozen or so rolls of the HP5 one day soon.
127 is eminently do-able with a bit of patience. You don't have to resort to cutting down 120 but that's a viable option if all else fails.
Here's one from the Yashica on Crossbird:
