I had a Lumix G3 for a bit, which I got last year for $300 with the kit 14-42mm lens. I found it more useful, and not much larger, than my first digital camera (a Nikon Coolpix 5700; I can't believe I paid $1200 for that camera...). I recently sold the G3 because, as with the old Coolpix, I didn't like the electronic viewfinder. I'm very used to the view through a "real" SLR like my Nikon F3. Also I really prefer to use film whenever possible, and I just wasn't using the G3... But it was a great little camera, very portable, with good image quality. And all the m4/3 cameras have the ability to mount just about any lens you can find, with the right adapter. Nice for someone like me with a collection of screw-mount Takumars and other oddball m42 lenses.
