I don't know that you can buy anything but parabolics now. The pros to parabolics is that with the shape of the ski you get a lot more ski for a lot less length which means you don't need a ridiculously long pair anymore.
The biggest piece of advice I can give you about buying equipment is that, at your level, you want your boots to cost more than your skis. By this I mean, buy a nice set of boots and a decent, even used pair, of skis. If you don't have a pair of good-fitting boots, you might as well not ski. And look in to getting custom orthotics in your boots. Your feet will thank you.
