Great price, no trouble
I bought a Sony RX10 mark ii from Gadget Circuit because it was the lowest price online I could find that looked like a reputable source (aka, when I googled the name and looked for customer reviews, they were decent)... The camera arrived quickly and fully functional. I was a little concerned when it arrived because the it seemed like the Sony packaging may have been opened before, but everything was included and brand new, so I can't really complain. The bottom line: I saved $200. That's a win in my book :)
