Definitely what I've learnt from experience is that windsurfing is one of those sports where you "grow out" equipment as you progress. ie. I year ago I thought a 130l board wasn't going to be buoyant enough for me and now I'm considering an 86l board.
Conclusion: Buy second hand until you reach a point where you're really gonna enjoy the new kit right off the bat.
Great thing with second hand material too is that you have a lot less stress. If you scratch it here or there it doesn't really matter.
On the contrary, if you get a Futura (say 133 or 144) now, when you progress you can keep that as your light wind board and get a smaller one for stronger wind.
It is your money but definitely have a look around for second hand kit, you can find some really good stuff if you know where to look.
