I'm not a fan on my Marker 1800s. They don't seem to have much elasticity, so I have to keep them at a higher din and they still pre-release, yet it hurts my ankle when I hook a tip in slalom. My Rossi FKS 185s are just the opposite, with a ton of elasticity. I would look into those, and I've heard good things about Tyrolias as well. I would stay away from Atomic Race bindings (the old-style ones), given that they're heavy as hell. Salomons are well-liked, but as long as they're the all-metal 916s or higher. I had a pair of old, plastic 914s and the screws on the toe wings stripped out. I'm not sure if it's still a problem.
So bottom line, do what's cheapest and has the DIN range you need, but choose others over Marker, Atomic Race and plastic Salomons.
