Andy, I read loads of reviews too. I already had a GX100 a few years ago so was fairly familiar with Ricoh. I was initially put off by the modules but it's no worse than buying the Leica X1 with it's fixed 35mm and at least the GX100 looks like having some more options soon. It's also build very sturdily. I think I'll probably have to shell out for an evf come the Summer as the screen is quite hard to see in bright sunlight (NEX 5 is better in this regard). I'm very happy with it and it takes great ooc b & w jpegs. I can't really fault it so far. The reviews I read for the A12's were good but most thought they were too expensive and this may be so but then I've already had my Leica X1 repaired within it's first 6 months and that was almost twice the price!
