I own a GF3 with the 14-42mm X lens. I bought a used (like new) G3 about 4 months ago, and haven't touched my GF3 since. I use to roll my eyes at all the comments regarding the need for a viewfinder, but always pick up my G3 rather than my GF3 now. I even take it out of full auto on occasion!!
Still - a great price for the package, and a very cost-efficient way to enter the world of interchangeable lens cameras, with something that is quite small.
