I think what you want is a race stock slalom ski from any of several manufacturers; Atomic, Rossi, Head, Volkl, Salomon, Fischer, Stockli, Nordica, etc. Almost every one of them will be a powerful carver with wood sandwich construction. There have been very few truly significant changes in that kind of ski for years. What that means is that if you can find an unmounted or lightly used pair from a couple of years ago, you're getting basically the same ski they're selling now.
Do you live near a ski resort with an active race program? If you do, a couple of phone calls can usually hook you up with some racer types looking to get rid of "excess" skis. If you get introduced to a local racing crowd, you'll find that skis like that are always trading hands.
Another alternative would be something like Ebay. I don't know what the European equivalent would be, but here are three listings I found searching Ebay for "slalom race ski". Any of these would do what you want:
Good luck and have fun. That kind of ski is a riot.
