Replying to New park skis

I got four hundred dollars for Christmas and as of yesterday my old park skis only have one edge underfoot. I am six foot 180 pounds and am looking for a relatively inexspensive park ski. I am more of a mountain skier seeing as I live in montana but i probably spend at least thirty days a year hitting park or preseason rail set ups. the most important thing in looking for these skis is a ski that has strong sidewalls, wont lose edge, and can take a beating.
