Ebay has the best prices of anywhere but you have to make sure you can trust the seller. I bought a pair of brand new fischer race sc's this season for my dad for $200. www.untracked.com
also has very good prices on ski equipement. DEpending onw aht youre looking for and how soon you want it i would look at ebay. Recently the number of skis being sold on ebay has dropped but i would expect it to pick up again in the fall. once that happens you should be able to find pretty much anything you want, its just a matter of watching the auctions so you can be sure to get the ebst deal there is. Also you might want to try www.skiershop.com
(this site recently changed to a new domain whihc i dont have right off hand, but im pretty sure there is a link).
well here is a list of shops:www.skidealer.comwww.skitrader.comwww.buyskis.comwww.snowcountrysports.comwww.untracked.comwww.mprattesport.comwww.kitsapsports.comwww.geardirect.comwww.comorsports.comwww.fiorinisports.com
hope those help out a little, i havent been to them in awhile so id ont knwo what they are currently carrying or what prices they are at, but those are the best i know of. I have bought skis from skitrader and i would highly reccommend them (they are a canadian shop so you can get the skis pretty cheap with the exchange rate).
