What are great skis for both the terrain park and regular downhill runs?

I am an intermediate skier and have been skiing for about 4 years. I love going down regular runs, and love the terrain park too. I want to be able to land backwards off jumps, and still be able to go down downhill runs without it being much harder than riding on normal skis. I also would like it if the skis were under $250, used or new. Thanks
