I wouldn't write off ski brands. atomic, salomon, rossignol, and k2 have come out with good stuff. k2 has just the biggest footprint so far, and deservedly so given their commitment; what I mean is that I would pretty much trust anything from k2, but I would do more research regarding products from the others...but not by a whole lot.
I have been a huge fan of the top end Rossi boards, ski companies can make a perfectly good snowboard, much of the technology, concepts and manufacturing processes are transferable. At this point Skiing and Snowboarding are taking tech from each other and its helping both sports grow.
