In reply to baker:
For colour neg for a couple of years I just used a local Tesco because they happened to have a reasonably well maintained minilab and were super cheap, like £4 for process-and-print (36 exp at 6*4) and another £2 for a CD (1800*1200). Often a next-day service. If lucky it would be ready in an hour without paying the 1-hour service, if they weren't busy. Then the prices crept up and I decided 1800*1200 was a little bit lo-res, so I found the Fuji Burnley place. I had used Peak Imaging for slides and b&w but to get them to scan at more than 1800 * 1200 started to get expensive. Burnley's standard scan is 3000 * 2000 which makes quite a difference.
Some Tesco and Asda apparently will do process-and-scan only (no prints) and put 4 films' worth onto a CD for peanuts, but the ones local to me don't do this. Some Morrisons do a service too.
