Replying to Invaders

Okay, so I'm thinkin about getting the invaders. They werent my number 1 choice but from what i have heard they are a pretty good ski and my friend is selling a pair and i can probly get them for pretty cheap. Do you think that these would do the job in groomers, powder, moguls, park and etc. I'm getting them for a good price and I'm wondering if its worth it to save up some more money for other skis. I really want a ski that will do fine everywhere.
