If I were you I'd avoid anything that says 'flexible tree' and stick to something with an interchangeable gullet.
A few (cheaper) saddle brands advertise 'flexible tree - fits most horses' but it's just a gimmick that doesn't really work. If the tree flexes enough to fit from a medium to an extra-wide (for example) it'll rock on the horse and potentially give it a sore back.
Personally I'd keep my eye open for a Thorowgood T6 (Whittaker) jumping saddle which they did in a 16 1/2", has a changeable gullet, a decent panel which can be flocked to fit, and shouldn't break the bank if you can find a used one. Unfortunately it looks like they've stopped making them now :(
