Wintecs have always been decent saddles and have been around for a long time. I would never discourage someone from buying a Wintec but if you see the Fabtron and the Wintec together, the Fabron is a much higher quality saddle right down to the materials used.
One of my beginning saddles was a Wintec Close Contact. I showed in it, and everyone was surprised to see it was a Wintec, not a Bates. It is the same model. It has an Easy-Change-Gullet System, with interchangeable metal gullets that you can use to fit your horse. I bought mine for $499, but the prices have gone up since then.
If you're going for English, I'd say Wintec or Thorowgood. Those are the only two brands I trust.
Wintec's western saddle isn't as great. I would put it on the bottom of the list for western.
If you want a western saddle, I would consider Abetta, Big Horn, or Fabtron, in that order. All three are made in the USA on good trees. I have an Abetta and it lasted a long time and took a lot of use and abuse. It's still in working order, just not all that pretty, lol.
I'm strongly against Wintec. My western Wintec tree broke in field when I was going down hill (just couple years old and not that heavy used). I ended up flying over my horse head. Not fun. Another Wintec broke on my friend in two half. He said it was unforgettable experience to ride back home.
As far as I heard Big Horn is a decent synthetic saddle for trail riding.
