They look to be in better shape than the rentals I learned on. Rental stuff in the late 60's-early 70's was really bad. After using that stuff about a half-dozen times I broke down and bought my own sticks with step-in bindings and buckle boots. My skiing improved 1000% overnight.
My first learner skis were WWII surplus with bear-trap bindings. The cable bindings were an improvement. Cable bindings with that pivoting toe piece came next, then step in bindings. Well at least it's safer than screwing the boot to the ski.
