No, no, and NO! ANY leather saddle that retails for under $600 is NOT worth buying... You're much better off buying quality used equipment than cheap [email protected]
new equipment. Stick with name brands that currently retail for $600 and up, like Crosby, Collegiate, Bates, Stubben, Courbett, Passier, Kieffer, Ovation, HDR, etc. You want quality European or higher priced Argentine made saddles.
Or, you can go synthetic. Wintec and Thorowgood are the two best brands. Maxam is a line of thorowgood saddles that is sometimes adervertised used without mentioning that it is by Thorowgood. The HDR, Kincade, and Weaver synthetics are all crap.
Cheap English saddles are generally made in India, Pakistan, or China. They are made with thin, cardbaord-like leather that is (litterally) tanned with urine or other harsh chemicals. The color is then painted on, so cleaning is easy, but oil will not soak through the top surface properly (if at all). The hardwear on the saddles is usually inferior, made of metals that are full of impurities and much more likely to bend or break under stress. The tree is often fiberglass (or at least partially fiberglass) which is the worst material you can use for a saddle tree. It can warp and become brittle in extreme temperatures (over 90 degrees and below freezing), and can even crack or break.
You get what you pay for.
