Buy two $500 paddles.
Grab two old Windsurfer hulls.
Muck around for about a month getting your skills down (these boards will test you!!)
Once your hooked the the rest is history and you'll be ready to buy the right board.
They may seem expensive initially (often because it is another toy to try and fit in the grage) but once your hooked its all about getting the right board, not the price.
It worked for me!
