I've had the Tourmaster Intake for about three years now. It's basically the same jacket with Cordura instead of leather in the abrasion zones and less sporty graphics (like, the Intake is the Ford version and the GX Air is the Mercury).
I really like it. Fits well (thank God for tall sizes), vents well, is extremely versatile with the two liners, and it's held up well through thousands of miles. It's my go to jacket from Memorial Day to Labor Day. I wear a warmer three-quarter length jacket when it's colder. I'd go the same way again. In fact, I'm thinking about that Cortech jacket too.
The downsides in my opinion involve the waterproof/windproof liner. It's nylon, not something like Gore-Tex, so it doesn't breathe (works great for cool evenings, though). Also, all waterproof liners include that crummy compromise that the outside of the jacket gets soaked. It dries quickly, but you gotta get stuff out of your pockets and into the bags when the weather turns wet.
Overall, darn nice bang for the buck. It's a good deal.
