Brand of ski doesn't matter much with beginner/intermediate as much, but Dynastar and Volkl are generally considered highest quality; K2, Salomon, Atomic, Rossignol, etc. are all fine too.
Post your height, weight, age, athleticism, and experience and the braintrust here can confirm if you're making a good pick or not. Same for your wife (if she's small, I might actually have a pair to unload if I can find an upgrade for my wife)
