re: weather sealing, use the camera, it won't be an issue.
re: iq, I suspect some of the IQ comments on the PenFcome from people using the primes instead of the zooms.
It looks like you've figured out what you want in a second camera. It's a simple debate, a "backup", or "something different". Pen-F's show up on the used forum here often enough, and factory reconditions on getolympus every once in awhile. Looks like there's one at KEH.COM also
