I purchased one recently for $350 with the 14-42R and 40-150R, I sold both so my camera body cost me only about $180 for a brand new camera.
Paired with the 14mm F2.5, I've never had such an inexpensive combo produce such good results. The IBIS is flaky in my tests with a 45mm F1.8 so I generally leave it off unless I'm shooting in the dark. It's a cinch to turn on/off. I also bought a VF-4 which I love that it can take.
Best of all, I won't lose dynamic range by shooting above 1/500 like I would on a GM-1.
Only really took it out today for shooting.
