I am a fan of the Bates saddles (I own an Innova dressage saddle and a Caprilli Close Contact). Both have the adjustable gullet with the interchangable plates....that is a big plus for me. Both also have the CAIR system (air panels vs. foam, wool, or a combination of the 2). Some people like the air panels, some don't.
The Innova was close to $3,000.00 and the Caprilli was $1,600.00...both purchased new. If your budget is as high as $2,600.00, you may want to consider the high end french saddles...but you'd have to purchase used vs. new in that case though.
Saddle preference is a very personal thing, with many options available. Just be sure that what fits you also fits your horse.
