I have used these guys a few times, and I highly recommend them. They were generous enough to custom-cut leatherette for my modified Mamiya Super 23 (see profile image). In doing so, however, there was an error in my communication to them about something that had to be done to one of the leatherette pieces (I believe I had required a hole to not be cut out of the leatherette in spite of the pattern I sent them). In any case, they promptly fixed the issue, and shipped me a new piece of leatherette, cut to my request, free of charge.
