I found this on Craigslist in PA, specifically Pittsburgh; I don't know if it's in your price range or even near to where you're at, but hopefully, it'll give you so hope that you'll be able to score a good, affordable leather saddle soon: http://akroncanton.craigslist.org/bik/4017648797.html

P.S. I've been looking at Brooks as well. Too bad they're so spendy.
