I ordered direct from Corbin and it took about a week. Delivered via UPS. The important thing is that when you ordered it from them, they should have told you whether it was in stock or not. If you ordered custom piping/colors/studs etc., then they build it and it could take up to two weeks.
I, too, checked around and found that the prices were the same as ordering from the manufacturer.
Texxan, thanks for the link. They do have good prices compared to what I paid. The seat alone was about $90.00 cheaper. I couldn't find the backrest I ordered on their site but they probably carried it because it looks like they carried everything else. Guess the next time I need something I will ask what other people did first.
