I've had a number of PMs from my feeler post, and apparently there's plenty of interest in these skis so I'm going to offer them for sale.
They are the Kastle RX with the KTI plate and 14 DIN Kastle bindings (rebranded Marker). I hate parting with them, but these aren't getting as much love as they should so they should go to a new home. I think they are 2010 vintage, but are the same ski as the 2013 RX 12. Fantastic hard snow ski that grips like an ice skate, but is very user friendly and doesn't punish the user to much for bad input.
Bought them as used demos from a company out west. Don't think they had more than 15-20 days (if that) on them when I got them and I've put another 10-15 on them here in PA.
Tops are in great shape with only some light surface scratches and the two small chips shown on the close up of the tails. Bases are also in good shape with some light scratches and the one base repair shown in the close up picture. I repaired the damage at home when I purchased the skis with a p-tex candle and have had no issues with it since. The surface cracks in the p-tex cause no loss of performance. If it's a concern, a professional shop repair would only cost $15-25 dollars depending where you live.
Bindings are in great shape and will adjust to any boot with only a screwdriver. Binding design also allows you to dial in your preferred fore/aft position on the ski. Retail on just the bindings would be somewhere in the neighborhood of $350-400 new (if you could buy them).
$550 plus actual shipping cost. These are near $1500 new, and I paid $750-800 for them. If for some odd reason you don't want the bindings, I would sell the skis by themselves and keep the bindings.
