First ski help

If your serious about getting into skiing, find a pair of boots that fit well,get footbeds in them and go from there. Boots are the hard part. Skis are cheap and easy to find.
The main reason Im stressing boots first is they are the most important part of skiing.

Here's a recent thread on why you should get boots with footbeds.

But if you already got boots need a little more information. Your height, weight, (already established your beginner), more in the park or allmnt,Rocker or traditional,pow or trees?

Already have some ideas seeing your gonna be in Montana I assume.

Rent skis the first time if you've never skied before. Make sure you like it, and maybe get a feel of what type of skiing you'll be doing, as that will help determine what skis you want (i.e. park skis, aggressive hard charging skis, skis with off-piste/pow focus, etc)

Listen to 50Kal on boots. Go to a good bootfitter (Epicski has a great list of good bootfitters by location), get boots from them, have them heat moulded, and get custom footbeds. If you don't have enough money for everything right away, you can get custom footbeds later, but you should definitely get boots from a bootfitter, and get them heat moulded right away.

For skis, you probably want an all mountain twin tip at first. If you start skiing a lot you'll want something wider for pow days. For all mountain twins I'd go around 95mm width. I ski something much wider than that (117mm) most days, but as a beginner to skiing you won't want something that wide on anything but a pow day. If you ever decide to get a pair of pow skis as well, look in the 115-125mm range.

For specific skis, if you want an aggressive hard charging ski, something like the Dynastar Slicer would be good. If you want a softer more playful ski, something like the Line Chronic.
