I find it really hard to sell my equipment, as a matter of fact I don't (apart from what I consider really bad). I haven't bought all that much equipment that I consider really bad, I always attempt to work within the boundaries of what a certain lens or camera can do. If need be (and quite often it is so) I change my post processing workflow to suite the equipment. I think most people do this as equipment characteristics differ.
One afternoon I decided to get the old Panasonic GF1 out of the drawer and stick my favourtite kit lens on it; the Panasonic 14-45 f/3.5-5.6 kit lens. I still consider this the best kit lens ever made (although the Fujinon X 18-55 F2.8-4 lens is also a very good lens). One attraction of the m4/3 system is that the lenses are interchangeable with all the cameras made by Olympus and Panasonic. That, to me, is a great plus.
Right now I'm really struggling to get the correct colour from the newer Panasonic bodies but not with the Olympus cameras and since Panasonic has some good lenses lacking in the Olympus corner I just mount those on the Olympus bodies. I think the only Panasonic body I has really great colour from is the DMC-L1 which I still have and use with the PL 4/3 14-150 lens. A really remarkable combination. However at only 7.5MP it's not really competing with the newer models for resolution. Having said that I've printed out images at 80 x 60 cms and they look great.
