RE: New Surfer
JJ is giving you the best advice here.
Go to the NOKB school and take some lessons, get proficient with the basics, and then think about selecting a board.
What you need to get started in windsurfing is very different from what you may be sailing in a few weeks or months.
With good instruction, on good beginner gear, you will shorten the time it takes to be ready for the next level significantly.
Then you can buy a board for the next level.
Hope this helps,
