My Epicski price is $519 right now, so w/bindings could easily come in under $650. It depends on the bindings: "with bindings" is often with a cheesy, low-end binding that doesn't match with a high-end ski. Usually, they will specify the model if it is a desirable model. I have Tyroilia LD12's for an extra $120, or Mojo 11's for $115, Mojo 15's for $169, ect. These would all be suitable models for that ski.
Good luck with the demo. PM me if you want a pair. I still have a few left.
