Realistically, the dc2 is too cheap. And the em1 is not registrable, unless you're willing to fork out lots of money to get it mod plated and what not. Unless you know a person to chuck it over the pits in a very dodgy fashion, of which would get you defected hard if found out.

Not good examples, if I've ever seen them (based on price and brief description)

Also yes, 12k for am em1 with a b18c is stupidly expensive
