This is just like... your opinion, man.
I have the eva-1 and love it.
Feels cheap? how about feels lightweight? try shooting handheld a whole day with your UMP. Image looks amazing, only issue I really have with the camera is it's horrible monitor - solved it by using an external monitor and I'm still waiting for Panasonic to come out with a better solution.
This actually looks amazing for simple testimonials.
