Hey K-dog,
I'm new to the sport aswell,
Ive gotta aggree with Nebbian, your first planning experience will be a whole new side of addiction.
But back to the important stuff!
Well im very simular weight to you, and i learnt on a 155lt board, i never touched a bigger volume. And 7 weeks after testing out the board, i found myself sellign it for a small board 105lt (:
So heres my opinion, dont go wasting your money on a brand new 2010 board that wont even make it to winter. Go and buy a 2003-2008 Learning board/ Large Freeride board. 140-180lts.
I bought my board on special for $1240 and sold it for $800. There for it cost me 440 to rent it out for the 7 weeks, i rekon i could of done alot better if i didnt go and buy a "still new 2008" board.
Search all windsurfing sights and regularly check, as these learning boards disapear by the hour.
Now for your RIG = Mast, Sail, Boom, Ext
I'd say go straight to seabreeze.com.au
And find a tough wave sail from 4.5-6.0 in size, perhaps look for a "Complete Rig"
where you'll get all the pieces to the puzzle.
I would say dont bother with spending more than 500 on this sail, as it could likely get damaged in your learning stages and it may only come out again 5 times a year for the days with strong enough winds to suit such a small sail. I learnt on an Ezzy Sail, which are known to just be ridiculously tough, and will survive almost anything.
The only other big of advice i could give, is once your learning the basics. Go and get yourself some learning dvds and do your reading at,
