Well do you know exactly what you need? What are all the measurements? That will make looking on ebay
and craigslist much easier. If you know the measurements and can make sure the seller has the correct measurements (I get pics of them measuring) you can usually safely buy on ebay. Much more choices and the prices are good.
I would never spend 1k on a saddle but you have to know what you need and look for it. Seriously I asked everyone I knew if they had heard of saddles for sale.
