Losing your license is just like being 15 all over again... except this time you don't have your mum or dad to nag for a lift some where!

Anyway, don't just lock yourself into one brand because you learnt on them. I was learning on EH Beasts and Slingshot Fuel's, as well as flying a Naish Aero II i picked up off a mate and one thing i've discovered is that whatever your flying... your still kitesurfing! Any of the '06 or newer bow/SLE/hybrids will do you just fine in terms of safety features, so aside from that just pick one you like the look of and can afford.
Some people (instructors with vested interests) will try and convince you to buy brand new but with the price of last years gear being ~60-70% of new, and 2 year old gear being ~50%... it made sense to be to buy a 'last seasons' kite until i knew what i was doing, knew how to fly, and most importantly knew what sort of kite i wanted!
Keep an eye out on the Seabreeze Buy & Sell and you'll pick yourself up a '06+ bow/SLE/hybrid for ~$700 without much trouble. All up, you can get your own gear for ~$1100-1400 which is still far less than the price of most new kites!
Congrats on your new found adrenalin outlet and look forward to seeing you on the water soon.
