So, my idea is basically this. Skiing is expensive, especially if you are buying all new gear for somebody. On the whole, I'd say pretty tremendous advances have happened in skis the last few years, but that doesn't mean that there aren't older skis that aren't great skis. Still, there is also older equipment that just plain sucks, and this is the stuff that tends to make up 85% of consignment shops and ski swaps (almost always for ridiculous prices).
So lets talk about older model skis (5+ years) that still offer good performance, even by today's standards. I'm not really referring to classic ski equipment, but equipment an average person in the right conditions could really enjoy.
I think a list would be very appealing to people. Maybe somebody skiing primarily hard snow wants to pick up a cheap fat ski for use 3 times a year on a vacation to a larger mountain. In my case, I'd probably like a better hard snow ski for the 2-3 days out of the year where EVERYTHING is boilerplate where I ski, but I can't justify spending "real" money on a ski that just won't be used.
In many cases, we advise people buying their first ski gear on a budget to budget boots first. It would be nice if there was a list of recommended equipment to look for in used skis.
So, to get things rolling, here are two of my recommendations for great older skis.
K2 Seth Pistols: twin-tip, 95 Waist, really, really versatile as an all mountain ski.
Volkl Supersport T50/5 star: 68 mm waist. A very good frontside carving ski.
