Replying to Atomic E5 w/ Marker M28V. Should these skis ride?

Hi Newschoolers, I have the opportunity to get these skis for $50 bucks. Getting for a beginner, 3rd year skier, 12yo, 5'6", 120#. Atomic E5 Beta, with Marker M28V. The bindings need to be moved to accommodate a smaller boot buy about 3/4" or so. They look to me to be in good shape, with sharp edges, not beat up. The seller said they were 5 years old, tho they look older. The bindings look in good shape but definitely used and entry level for sure. They appear to operate but need some lube too. Will they be worth getting the bindings moved and used for a few years until her skill level increases? Any obvious danger. We want to take them to the shop before using and get them tuned/waxed.
