Mark,
I dropped around $800.00 for the seat. The haze shown on the Russell site(see Magic's post above) is mine. They list the seat cover as baby alligator, it is the quill ostrich. Hence, the added cost.
I was without the seat for about 4 weeks. That includes the time shipping to them, the build, and the return. Katy said that they could include the factory backrest. I choose to not use it, because of my height. You might consider allowing them to recover the factory backrest to get a better match. The ostrich leather is miles ahead of the factory quality. They saved the seat heaters at no additional cost. However, they had to locate the plugs further back and I had to add length to the wiring in order to hook them up.
All that said, I remain very pleased with the seat. The comfort in the ride was worth the coin. Katy will work very close with you to make sure you get the right fit. Each seat is built for the individual. I have had many compliments from the "seasoned riders". The photos do not do the seat justice.
Good luck and safe riding!
Ken
