I'm looking at getting a G9X but I have a question about it. On my travels I've seen it elsewhere (obv can't post links) but there are 2 of them, one is a COD one and the other is the silver one. It's just the COD one is £30 cheaper than the silver one. Is there more than one version of the G9X? I thought there was just the G9 and then the G9X and the only difference between them was the DPI. I take it the COD one is an older model?
