The current trend is come out with new models every year with a few incremental improvements. So there is a deal like this pretty much every 6 months. For example, I got in on the Oly Spring blow out of the E-PM2 and, after I sold off the 14-42 and 40-150 lenses that came with it, my net price for the E-PM2 was around $99.
I keep thinking about buying a GF1. I'm pretty sure I remember it being better than it actually was (compared to newer bodies). But I have no such temptation for other GFs. Not bad cameras, just lack the nostalgia factor of the GF1.
