Update; since I was planning to sell my Choc Mini after buying the 660c anyway, I'm willing to trade my Noppoo Choc Mini White Version MX Blacks w/ PBT caps + cash (~$100) for the fc660c.
It's been used lightly for about a month and half, still in like new condition.
EDIT: Only thing about the Choc is that the led for the caps lock doesn't work, but it came like that.
