I can also vouch for Courbette saddles, I 've had two and they were well made and lasted for years.
Depending on the depth of the seat, it's hard to say what will fit you. The hand width is good guide. A close contact 17" is much bigger than an all-purpose 17". The position of the knee rolls also makes a difference. You just have to try differnt saddles in the tack shop.
Getting a saddle to fit the horse can be much more difficult, you should get a saddler to evaluate the fit and make adjustments. It makes a world of difference to your horse and his attitude. Kind of like you wearing the wrong shoes. They might be the right size, but if they pinch your foot, it's awful.
I really like the Thorogood synthetic saddles. They are well made, and the new ones come with an adjustable gullet. They also come in high wither, standard, cob, narrow, wide, and extra wide. Easy to care for, and the seat is very grippy, for a secure feeling. Knee blocks are adjustable and removeable. The older model I have has 4 billets, the new ones have moveable billets so you can set the girth slightly forward or back, if you need to adjust the saddle on your horse's back.
