Good to hear from you Pricey. I know of a good GS500, asking price is A$1500, it's in Ballarat, I was tempted myself but I've got too many bikes! Let me know if you're interested and I'll get the owner's details.
(I could check it out for you if you like).
How north of central are you? VJMC Ballarat guys are worth hooking up with, but you may be too far north.
