The guy on Ebay just offers the seat cover but you can build your own seat and the price is not bad.

Looks like they offer two saddles and three seat covers at least on their website. I don't think the covers would be a big deal in helping with the seat, but the saddles look nice. Unfortunately, won't know until you ride a few hours in one though. Try here to see the options better:
