I watched a few on ebay and they seem to sell easily for £400 often upto £500 (was the black gp ones i was looking at) the key seems to be to start them with a low price. Saddles direct buy saddles as well and part exchange not sure what sort of price they would give you? http://www.saddlesdirect.co.uk/GP-VSD-Saddles/1/listing.html
I bought one about 6 month ago for £400, black 16.5" GP fitted with black gullet in perfect condition. Literally i think it had only been tried once or twice!!
i brought a Brand New Bates Saddle the other week with The Cair System.cost me £990.00 should have been £1100 Bargain!! its amazing the love itsoo much!
much better than the WOW Saddle!
