Stubbens are very nice. =]
I picked up a Kieffer saddle in excellent condition for $500. She "didn't know" the model (It was printed clearly on the flap.... o.O ), and since it's a higher-end model, apparently, I lucked out. =] I rode in a few Kieffer Wein saddles, and I liked those, too. The older Kieffers are the ones that I prefer to the newer ones. They hold up wonderfully and mine is SUPER comfy. AND you can find a bunch used online! =] If you're looking for new, though, they're well over $1,000.
I also liked the Karl Niedersuss saddles, those go for about $600-$800 used in nice condition, too.
