I found an older Stubben for $99.00 on Craigslist. If someone else doesn't snatch it up, it may just be coming to my house.
Have you tried Craigslist? That's where I found my last 3 saddles (all Stubbens), and none of them were uber-expensive.
When I'm looking for saddles, I go to Ad Hunt'r which searches all Craigslist in the US. If you don't mind paying shipping fees, you can find some really great bargains.
