Hi Tom,
I also bought some of this stock off eBay. I had it processed at Alphacine in Seattle. They said it was a bit tricky, but no problem.
I would give them a call re. chemistry / timings etc. They are pretty helpful.
This stock, for the price, is pretty good I think. It didn't have the contrast of 7222 but it was good in low light and still looked nice.
Cheers, Matt
