If you want them new, you will have a very hard time finding them. Id say the cheapest you should go is $250. Volkl skis get pretty cheap on backcountry.com
If you want new your best bet is to look for previous year models of skis that are already cheap on evo and backcountry and stuff in the outlet section
I highly recommend hitting up a ski swap if you have one in your town always hella deals at mine, if not I'm sure the interwebs will be able to deliver a good enough deal.
