Being in Australia, I bought mine from
www.teds.com.au. I found it was a good price for the body and two sigma lenses.
They did two packages - one with a 18-50 and a 55-200mm pair of lenses, the other with 24-70 and 70-300mm. I ordered the former, but the latter turned up. I sent it back and they sorted it out right away. I also picked up a tripod and extended warrantee covering the body and lenses.
I look forward to hunting around the pawn shops and op-shops for my new pentax lenses.
