Too bad I'm living in spain, and the Ilford distributor is in Madrid, I'm living near Barcelona (I believe there are good labs there though). Finding the envelopes seems to be hard, and bit expensive.
But I'm sure that Ilford's service will be better for B&W than any lab 100km from here. I find far more convenient leaving the film on the mail and have it again 10 days after, than go to BCN, leave the film, and return another day.
Edit [you can jump the text below, it's just a film shooter complain about his lab]
The lab where I develop my prints, just sends it to their base and they develop, scan and print digitally that with color, but I believe it's the same for B&W. Which is crap (allow me the expression). I would like to find a nice lab where developing is at least done with something decent for B&W, with enlarger (optically, was it?).
[Complain finishes here]
Let's see if carnival arrives here, and can give an excuse for try Ilford film. I hope HP5 will do enough at asa 400
I wish to get a darkroom someday (student, so I'm poor ATM), because the local lab makes you pay double for push process any film (so 24€ per 36exp roll at 4x6" prints). And, I find interesting the DIY way.
Ah bad, I ended making a complaining post, not a praise.
