Currently there is a bike on eBay I'm rather interested in, however it is in Horningsea Park, which I believe in the Hoxton Park/Casula area.
However seeing as I'm a)in Canberra, and b) only one-handed at the moment - it kinda makes it impractical for me to head up there.
And I'm sure you guys know more about modern Kwaka's than I do.
Shoot me a PM or whatever if you're in that neck of the woods, and might be able to help a cripple out

Cheers,
Lurch
