Replying to Looking for powder skis 160 - 170

I'm going on a trip in a couple months and need some powder skis, I'd like to keep the price as low as possible (preferably under 150$) as I'm a high-school student and won't get to use them that ofter. Used is what I'm looking for, I don't care how beat up these bad boys are as long as their decent skis, usable, and cheap. I don't have a lot to trade but maybe we could work something out, please let me know. size 160-170
