As I and a few others have said before, fair play to them for moving away to somewhere they both love and wanted to live, and are now continuing their passion for film and developing in their new home. I like them as people and as long as it is feasible, I will continue to send my film to them because their service is excellent and I really liked the results that I got from them. The costs will probably work out cheaper than Carmencita for me, even with the slightly higher postage, it just means I can't send single rolls for the price of a first class stamp as I used to when they were UK based.
Also, I know a few people who used RPL or Indie Film Lab, both of whom are U.S. based and their prices are way, way more expensive.
Oh and, if I could move to Canada, I would be there in a heartbeat.
