There are 2 levels of saddles.
There are the semi-custom saddles that are sold by brand reps who call themselves saddle fitters but very often have minimal training. The selling point is that the saddle is customized to you and your horse. However lots of these reps over promise to make a sale and if you are a naieve saddle buyer you may not catch the problems until well after the sale.
Major wool flocked brands include County, Stubben, Black Country, Passier (mostly British and German). There’s more. I’m in Canada so the ballpark figure here is about $5000 for new semi custom. In the US I’d figure a bit less, maybe $4000.
Semi custom saddles do not hold their value that well. They are excellent quality but much of the value is in the customization. In geberal they sell second hand for about half of retail.
Right now the trend in jumping is French semi custom foam panel saddles, and they are considerably more expensive, in the $10,000 range in Canada, so probably about $7000 in the US.
The other type of saddle is the budget saddle, sold in tack stores, that may have an adjustable wither gullet. They retail for under $2000. I ignore them.
Thd thing is, in none of the above scenarios do you necessarily get access to a qualified saddle fitter. You get access to a Rep who had weekend training in how to put together specs for the factory to make your semi custom design. Some reps are OK, and some are appalling, and some companies that make excellent saddles nevertheless teach their reps untruths about fitting so they can make a sale.
Looking at all the above, my solution has been to find an actual qualified Master Saddle Fitter to help me evaluate and then reflock good condition second hand quality saddles. If paying $5000 would guarantee perfect fit, that would be one thing. But it doesnt, and I’m unimpressed with the brand reps locally. When they inflate their credentials, when I see peculiar handiwork (overstuffed panels, uneven panels, etc), when they boast about fitting 12 horses a day, when I see folks pay top dollar for a saddle that bridges or their butt is hanging over the cantle, when they say “our saddles can be adjusted to fit any horse,” I give them a wide berth. This is a compendium of a number of local reps I’ve observed over the years.
