lol i just ordered a custom antares for my horse and I said to my husband, "(sigh) I have to sell my old butet now to pay the balance on my antares." DH replied, "No don't sell it. You never know. You may get another horse next year who will fit into your Butet"
If the saddle is one you will use, and it is a good deal, then go for it.
Remember saddles don't eat. But there are things that can harm them. So use wisdom in buying one more.
I use an old gym sock with the elastic worn out and fill it with moth balls. I tie off the end with a rubber bacd and put it down the gullet of the saddle. It keeps mice and rats away from the saddle and keep the moths out too.
