I ordered a Samsung NX200 from Amazon, and it arrived today. I saved $150 off MSRP, paid no tax and received free shipping. Amazon is great!
I've taken a couple photographs with the NX200 just figuring out how it works, and it seems pretty impressive so far.
The autofocus seems slow in low-light situations, but manual focus is a breeze (and more accurate anyway). Autofocus works quickly when there is plenty of light. I've experienced no other issues thus far.
I'll post more photographs and a full review in the days to come.
