Rossignol Freeski2 120 - $219.99
Marker Griffon - $229.99
Salomon STH 12 - $269.99
These binders all have reinforced heels (one of the first failure points on traditional bindings). The Marker is the only option from above that doesn't have an upward (vertical) toe release so you don't pop out on a backseat landing. It definitely favors retention over release. Both Rossi and Salomon make bindings like that but only feature it on their highest end models (Freeski2 150/180, FKS 180, STH 16).
