Of course, I love my Corriente, but I think they are just a couple hundred out of your price range. They normally start at $650.
I can attest to the quality of Simco saddles though. I have a roping saddle from them that is very well made and has been durable. It's not very comfortable for me, but I'm like Cori and haven't found a roping saddle yet that is comfortable. I have never ridden in a Wade tree saddle but the good thing about ranch saddles is that they are shaped for all day comfort, even when they have a hard seat.
Other than that, I won't be much help because the only other saddles I have ever really ridden in are 35 year old Billy Cook roping saddles.
