Hi Kev,
The archives within this forum will give you a lot of the answers you are looking for.
As for budget, 2K will get you either a wing or a motor. You will be lucky to get both.
I suggest you pick a school that also lends kit (normally if you break it you pay for it system)
If you start with a school, after passing your training the instructor will normally guide you in the right direction for a complete setup.
Lastly the kit is sold with your weight in mind more than your wonga.
My thoughts, but please delve into past posts for anymore info.
Mike.
Good hunting
