There is a Dutch brand called Lepper, and I have one of their classic springers on one of my bikes. I bought it from a dealer on eBay a number of years ago for about $35, but I doubt that is the normal selling price for those saddles. They are beautiful.
You can find some of the Brooks lookalikes out of India that are reasonably priced. I have an Avon saddle on one of my Raleighs. The rear springs on that one were too soft, and actually bent a bit so I replaced them with a set from an old Brooks saddle. But the price was right, in the $20 range.
