I would highly recommend you add Raiden to your list. They are the binding brand of Nitro and make some great stuff, not to mention being a US company. Got my gf a set of their Lynx binders last year, and she loves them to death. Only issue has been that the color has bled onto her white boots, but it's partially her own fault for getting white boots right? LOL It's a softer more forgiving binding, but even if you're looking for something with a stiffer flex, I'd sugest their Eris model.
