I had a terrible experience with KME about a year ago, where I'd sent my suit to have the zipper replaced. I will _never_ use them again. A trivially simple zipper replacement took over three months to come back to me. They first "lost" the suit for about a month, then they claimed they didn't have staff to fix it, and then, finally, after calling again, they had to "order a new zipper."
When I finally got the suit back three months later, they'd put the zipper in upside down (it's a diagonal zip across the front.) Two weeks later, when I got the suit back the second time, they had the audacity to charge me full price for the whole thing -- after three months and a major screwup, that was just asinine.
The quality of the replacement work was really poor, too; the zipper was installed slightly crooked, making it darn near impossible to completely close the "over-zipper" which protects it. They also neglected to put one of the "pull tabs" back in place that you hold on to when self-donning to keep the suit taut. All in all, it was the worst scuba gear experience I've ever had.
I send stuff out to Superior Drysuit Repair in Minnesota, now, when I need work done. They did major neoprene alterations for me on a Diving Concepts suit, and the work looked better than the factory assembly. Top notch, and they apparently have a better sense of top and bottom, as the pieces were all in the right place
Simple things, like latex wrist and neck seals, can be done by just about any of the major shops in town, in house. No need to go to a specialized drysuit place just to glue on a seal.
