I got an open box G10 from Best Buy for $999 and so far I really like it. I've got a HG20 and a HC1 Sony (mostly to play my old tapes). The G10 is really incredible, but even at $1000 I'm debating on getting the M40 for less than $500. Anyone go from the G10 to the H40 and happy about it? I've read about different lens quality and of course the wide angle lens on the G10 as some of the biggest selling points. I've never seen low light video look as good as it does on the G10. I mostly tape my two toddler boys and vacations.
I searched the MXX and G10 forum and didn't find anything conclusive of someone testing both.
