Dwayne's found more ways to get the negatives dirty or to improperly set the enlarger filters during printing on a regular basis than any other photo processor I have dealt with. I got tired of paying to ship everything back to be reworked. Besides they specialized in not refunding my reshipping costs. They are free to go out of business as soon as they can.
Humm, I've had exactly one real processing problem (as opposed to printing) in probably a couple of hundred rolls sent to them, a single scratched Kodachrome frame. The fact it's a shot of my elderly mother and my then-fiance didn't help, but it was only one. The prints are generally though not always fine, with a "not always" rate considerably better than I've experienced in the old days with most drop off labs.
Their scans kind of suck, I agree with that, but they are cheap and I don't have a film scanner suitable for 35mm or 120.
