Be careful not to get caught up on the "aesthetic value" of a saddle, as it might be pretty and blingy but it will either fall apart or will hurt your horses back. Whatever you buy it has to fit and I caution buying it off the internet as you can not try it on. If you can try on a few saddles from somewhere with a saddle fitter they can tell you what to look for in terms of bars and gullet, etc. For example my horse has a short back so rounded skirt would be best for him, and he is narrow up front with a bit of a wither. Not all saddles will fit him. I would honestly find a saddle that is for sale locally so you can try it on and have it looked at on your horses back before buying. You could end up with a very sore horse.
My trainer had been riding my horse last week and then I hopped on my horse for a bit and didn't want to change out to my rigging so I rode in his saddle. Saddle was old, dirty and didn't look like anything special at all, and when I rode in for awhile I noticed that my horse was moving a lot better and also I loved how comfortable it was compared to mine. I thought I liked mine which is a crates until I rode in his. Not pretty, but really good saddle.
