not sure id bother with a g1x, not saying its a bad camera though. depends what your after.
if you want great quality then maybe a csc mirorless camera, olympus have some inexpensive deals around, you might also pickup a good deal on a sony nex. smaler with more options
if portability is what you want then you can get a sony rx 100 for g1x money. or half that and get the excellent canon s100
g1x prety chunky, you might get an nikon 3200 dslr for that
like i said, depends what you want, soo many options
this is useful too
