Busa chain. Where & how much ??

[Natcam]

Hi all.
Its that time (30,000k's) and I need a new chain. I have some new sprockets in the shed, but want to know where from, and how much should I pay for a new chain.

If anybody knows of a good place thats priced right, please direct me. I will need it fitted as well.

Standard swing arm, no drag racing, or track days (yet ) but I love a bargain.

I am based in Newcastle, but could ride to Sydney.

Thanks in advance.
