they send you right back to the LDS to send it to USIA. I'm not very happy with my LDS right now, and I didn't want to (a) rely on them to mail my 1800+ dollar suit to USIA for the seals, either in a timely fashion or a safe, secure fashion, and (b) pay the LDS their pound of flesh for the experience, especiallly when they haven't been doing all that good a job at getting things done in the time frame they tell me.
I'm not much of a do-it-yourselfer, and finding seals ain't all that easy anyway, but I got talked into letting the LDS install them instead of sending it to USIA. That took three plus weeks when it was promised in one, and I didn't have time to test the suit out in a pool before a trip, and my nervousness over the wait and the lack of testing helped spoil an otherwise decent trip.
I asked USIA about this in a post on this board, and basically they're protecting their dealer network, which IMHO is tantamount to saying screw the owner.
All in all, it's a nice suit, but Jeez, if I gotta go through the LDS to get service, forget it. I now have been forced to become a do-it-yourselfer, and I'm not too happy about it.
So, if you don't want to be married to an LDS, and you're not a do-it-yourselfer, consider my plight. If you LOVE your LDS that sells USIA, can't imagine them doing anything on earth to make you switch your allegiance, and don't mind paying a bunch of money to an LDS to mail a suit for you, use USIA.
There ARE drysuit repair companies that will repair seals, but I'd rather send it to the manaufacturer, especially when they provide the service as USIA does (albeit throught dealers, but that could and should be modified). This should be part of the benefits of picking USIA over another.
Just my two cents, and I'm not sure what other manufacturers do, but I'd sure consider someone else who gives better customer service to the customer, not the dealers.
