ZX What?!

The days on my P restrictions are almost up and as such I'll be able to upgrade in the beginning of 2006. The GPX as basic as it is has began a bit of a love-affair with the lime green brand for me and of course that leaves me wondering what higher capacity kwakka I should upgrade to.. Price is a bit of a concern I'm trying to factor in the power - low price ratio.
I'm trying to decide between the ZXR750, the ZX6R and the ZX7R. So far I'm loving the ZX7R (we're talking 97/98 models) that go for around 7K.
Then there's the ZX6R which in my price range are 96/97 models between 5-6K. On the downside however the 6 isn't as aggressively styled and has a reputation for being more of a tourer.
The underdog is the ZXR750 which has a happy price of 5K or less but is getting old and perhaps a bit cumbersome?
What thoughts do you guys have on the best budget, green fang machine?
