Frau, head here www.skimag.com
and click on "gear finder" on the left side of the page. There are pages and pages of gear reviews for 2006 and past years too.
Don't pay attention to the prices...all is retail here, and you should be able to find everything for (at most) 1/2 of what you see here. The last 3 pairs of skis I bought was on e-bay, and all were $ 400 or less with bindings.
I agree with most here that favor a narrower waist ski for eastern conditions. I would try to stay in the 64-70 range for the underfoot dimension. Both pairs that I ski on are 68 underfoot and work well on the hard stuff and manage a little float in powder. Try to keep the tip dimension in the 108 + range and wider there equals better float in powder and turnier (in general) on groomed.
Oh yeah....shoot for around 160 cm or so.
