yes me too. I only use mail.
For 35mm I always go to Photo Express. http://www.photo-express.co.uk/
Really quick turn around, 2000x3000 D&scan for £4.50/film and the quality is good. Price *includes* return postage
For (a relatively new) MF shooter, for 120, I have used a few, but the place that is going to get my repeat business as best compromise on cost/quality for the time being is Spectrum
http://www.spectrumphotolabs.co.uk/content/about.htm. approx 2100x2100 develop & scan £8.60/film + £4.00 per order P&P, although I would like to find a higher resolution scan for the same cost.
