Big Kev's 05 blue 12r will be on the market very soon Barra.  
 
Pro's 
I think they are a BEST of the UBER Sprorts bikes. 
Ideal for the "larger" & possibly more confident riders. 
They blast through gentle corners at insane speeds better then just about naything you can buy & do it 2 up without a drama.
Low maintenance & Parts are cheapish. They have few mechanical drama's other then the clutch that i am aware of ?.
Brakes can be improved immensily with braided lines.
No one will EVER pass you while your going over 260ks or up a hill. 
Con's
For me they are a "barge with a big block shoved under the tank" i can't even get one off the sidestand unless the ground is flat  

 .  
"Dont lend it to Hammer" you wont get it back.
They are a lot more work in the tight stuff compared to the any other zx#r's.
Keeping up a supply of rear tyres to them.
Insurance can be a whack as well.
Oh and the small matter of poking around town in 2nd gear & keeping your licence  
 
Jonno coined the phrase a while back which sums it up nicely. 
"Ya Can't go past a 12"
