Wintec makes a very light synthetic trail saddle, but Colorado Saddlery makes beautiful durable trail and roping saddles. They can be heavy though so I would only use these with a quarter horse or stocker breed.
Used circle y's are the greatest in my opinion. I also know people who love tex tan which are very reasonably priced. Top of the line are Harris, Chavez, Billy Cook. Those are the saddles of my dreams. You wont find those for less than 2,000 in decent condition. I'd recommend circle y or tex tan to stay in price range.
I guess if I had to pick a dream saddle it would be a McCall. But if it meant giving up my Hereford with Wade tree, post horn, and bucking rolls - forget about it! I think that you could get a good argument going about saddles just like you could about which truck is best.
I second everything smrobs says about Corriente. I bought one because I could not find a good used FQHB saddle for my stocky mare. I'll mention that Corriente is a heavy saddle. But very comfy for me and my horse.
I love Court' Saddlery saddles, I have their Sharon Camarillo barrel saddle and love it. You should be able to find a used one in that price range. Everyone I've known that's had one liked it.
I gotta funny story about court's saddler. I was delivering a load of horses to Laramie, Wyoming. While we were up ther my pard and I decided to run over to Cheyenne, on the way we passed the "TACK SUPER STORE" (exactly the way the billboards read). They must of had 150 saddles in there and they were all built by Court's. I travelled 1700 miles to shop at a tack store stocked by a company that is 45 miles from my front door. On another note they burned to the ground a while back, but they are in their new permanent building and back to full capacity, sorry for the hijack.
Saddleonline does not have very good quality of saddles, I'm afraid.
How is your horse built? Will you need a wider saddle or more normal? If you want a very good quality saddle, I would lean towards a Crates, a Martin, Cactus, Double J - to name a few. I wouldn't pass up a good quality handmade made one by a good saddlemaker either. I would recommend you find the best to fit your horse first, then what works for you too.
