Out of curiosity, what op shops in the Brisbane area have you guys found to be the most reliable for finding Transformers?

I've done some Work for the Dole gigs at op shops (those days are long behind me, thankfully), and I found that different stores had very different types of "typical" donations- stuffed animals were common at some, while others would get Hot Wheels more often. I never found Transformers with any sort of regularity, though.
