You should be able to get a good GN250 for that price, or an FXR150. They both have about the same amount of power and performance, but the FXR150 looks cooler. If you want a higher performance bike you are looking at around $3000, or an absolute shitter for your price.
Try these ones on TradeMe:
2005 GN250, low kms
2004 GN250
Before you rubbish the bike on its looks or performance, know that it is almost universally agreed that the GN (or ginny) is the BEST learner's bike out there.
And remember, you're looking at around $1000 for gear on top of the bike. Doing what I did and buying the bike first and gear bit by bit probably isn't the best idea, just in case something happens.
Helmet: Cheap helmets mean you don't care about your head, buy one with a safety sticker, and NOT OFF TRADEME because then you can't tell sizing. Looking at around $200 and upwards for a decent one.
Jacket: You can get a good cordura jacket with armour for around $200
Pants: Ditto
Boots: Touring boots will set you back upwards of $150, sports boots (with plastic sliders everywhere) are about twice that but look cooler!!!
Good luck with the bike man, and welcome to KB 
Yours sincerely,

Did gyre and gimble in the wabe:
All mimsy were the borogoves,
And the mome raths outgrabe.
