I've seen a lot of people on this site post about the problems with getting 110 film processed. Well, if you live in the UK the answer is simple. The Co-op Pharmacy (which has brances everywhere) will still process colour 110 cassettes for 5, which considering how hard it is to get them processed is quite a good price. I expect they're just a bit behind the times and haven't noticed that production has been ended, but you dont even have to request it specially, its just a tick box on the form next to 35mm and APS. Only problem is I don't know if they do black and white. There's a map on their website where you can find where theres a branch in your area.
