I ride in a Crosby California Prix de Nations. My saddle has a longer flap and is a 17.5" to accomodate for my crazy long legs! I'm about 5'8" and my legs are over half of my body. I understand your frustration! New, the Crosby costs around $2000, but I got mine used for $500 with a bridle and 2 sets of reins too. The best part was it was barely used! I would suggest looking at used saddles to cut down the cost.
