some good deals on 10/11 / 11/12 skis floating around!
those skis even though brand new had been around for quite a few summers already...
I actually prefer to buy 2-year old "new" skis because they can usually be bought for less than half the price of new ones, and by that time they have been thoroughly tested and reviewed by dozens of people. As an example, this year I found a company selling some of last year's Line Influence 105s on line at a good discount, and a few pairs from the year before that for $200 less. With minimal research I discovered they were exactly the same ski with different top sheets.
Many of the small independent companies keep some models virtually unchanged for years, you just need to do a little homework to figure out if this (or next) year's model is really a material improvement. It is cool to have the latest equipment, but sometimes the extra $$ just buys you nothing more than the cool factor.
The only caveat is that sometimes the reason the skis were not sold is because of a defect. It is a good practice to always check that the serial numbers match, the edges are not wavy, etc. Always look a gift horse in the mouth.
Depends how crazy of a deal you're talking about, and how much you're really saving buying -2 or -3 season old skis versus just last season's skis. Just like many other model year things, the bulk of the depreciation kicks in just after 1 year. Then, if the ski has changed or if it was just topsheets.
