I'm like you Mike... when the right model comes along I'll buy one.
For me, "the right model" is going to be heavily weighted towards Nikon, for the BIG reason that I don't want to be into another system of lenses, flashes, and other accessories.
For Nikon to get this "right," they have to make a Nikon "PEN" compatible with the rest of the Nikon gear.
And oh yeah... my old OM. You just brought me my first big Monday morning smile.
