It took me six years, hundreds of riding days and a dozen boards to get to the point where I knew exactly what I wanted in a board and could articulate it to a builder. I bought a brand new Prior in 2002 when I first started hardbooting and really, it was a mistake. I had no idea what waist width I liked or radius, or stiffness or length. I should have waited until I had at least two full seasons of riding under my belt before I ordered a new board.
I would never suggest to a newbie that he/she should spend the money on a DonekcoilerpriorviruspogovolklF2. I would say buy a cheap but solid board that is appropriate for your weight. If you decide you like carving, buy more cheap, used boards and weed out ones that you don't like. Once you've settled into a style of riding, you will know your preferred specs. Then you order *The One*.
It's like dating. Your first date, you shouldn't be all that picky. His clothes are 10 years out of date, he needs a haircut, he slouches a bit. But hey, he owns a car, he's got a job and he doesn't smell. His name is Burton. Take him for a spin. Maybe you won't even like dating and would prefer to live alone with cats.
