Niche marketing is nothing new in the world of videos; Boulder's Video Station has been doing it for twenty years now. Yes, this is the place to find classics like Debbie Does Dallas, Deep Throat and Behind the Green Door, but a huge part of the store's 66,000-title inventory is made up of foreign, independent and avant-garde films. There's also a big documentary section; if you missed the basketball epic Hoop Dreams or the Academy Award-winning documentary Hearts and Minds, Video Station has them in stock. And if you want an obscure film -- say, Darby O'Gill and the Little People, starring a young Sean Connery fending off leprechauns --for your very own, this store has plenty of used tapes for sale. In fact, if you can't find your desired movie here, it doesn't exist.
