I've had similar experiences with them. I got someone else's order once by mistake, and within a day they had worked it all out with no effort from me. I've had great communication expediting shipments for rush delivery, and always get a personal response very rapidly when dealing with Mark and the others in the surplus store.
Frankly, they can't be beat for the product and availability through ebay rather than a distributor. Lots of great experiences with them.
