Are you taking any lessons?
Have you ever kited before?
Do us a favor and take lessons first.
Watch the latest wipeout video and you know why.
But, there is a lot of gear out there, you can get 08 gear for real cheap.
Don't get anything older. No reason even if you can get it for dirt cheap, go for the latest you can afford .
If you want a great deal, check with Eclipse. http://www.eclipsekiteboarding.net/
I use them so I might be a bit bias , sorry.
