All the skis you'll be interested in will be race or "skicross" skis. Most of the "skicross" skis are the same construction as the GS race skis (depends on the company of course), with a shorter radius (usually 15-17m depending on length) and slightly softer flex.
It depends on personal taste, but if you're going to want to occasionally take them in heavier crud or bumps I would go with a skicross, but if it's going to be 100% hardpack go with race skis (although I should note that a good GS ski and a strong skier will actually plow through crud thats not too deep very well IMO).
My primary suggestion is the Head i.XRC 1200 SW (the sidewall ski that was mentioned above). You might be able to get a deal on last year's 1100 SW - it's pretty much the exact same ski, very little difference.
