Rossignol Blast Jr. skis (105 cm) with bindings for $65 plus actual cost of shipping. These were used maybe 8 times in soft snow and twice on hardpack before my little guy outgrew them mid-season.
The edges are sharp (no burrs, no rock hits, etc.) and the skis are waxed. The tops have a few very light scratches, and the bottoms are in great shape (see photos). There is a small cosmetic blemish in the P-tex base, which does not have an effect on performance (see photos for details). The bindings look as if they were used only a couple of times and are in perfect working order. The heel pieces are adjustable, so they will fit almost any size boot for a child looking for this size ski.
Buying at this price is a lot less expensive than renting, and the quality of the equipment is typically much better. Besides, you can likely sell these skis next season for around the same price! My little guy has outgrown them, so grab them before they are gone!
