There is so much stuff on sale all over the place at ridiculous prices. Actually, on that site I was looking at you could get a Forum manual board, ride bindings, goggles, gloves, jacket, pants and new and pretty nice stuff for under $400. Everything you need to get started. Sizes are limited and colors might not be exactly what you want, but damn you could get started real cheap these days.
I think I paid almost $400 for my first used Board, binding, boot package from the local surf/skate shop back in 91'. My first board was awesome, it was one of those things from the 80s with a big ol square tail and pointy nose. I was so excited when I upgraded to my first brand new board ever, the 92' or 93' Burton Twin 58. That thing was a hell of a board and helped me progress a lot.
