I don't have any experience with their sprung saddles, but I do have a little experience with the non-sprung Gyes saddles sold by crowcycleco.com for about half-2/3 the cost of a brooks and have found them to be quite serviceable. Sure that's stretching into the used Brooks price range, but it's a saddle when you want it in a couple of different color options without spending the time scouring other sources and hoping to find something.
