I've had the MC2000 for years, recently got the NC2010 and it is streets ahead of the old model. 
I got one from ebay.de for £500 delivered, a 2011 unit. Integrated Parrot bluetooth and decent nav, nothing can compare at that price. 
It also shows info on the highline, and digital aircon/parking sensors if you have those fitted. 
Make sure it has all the kit (GPS antenna, TMC box, USB box etc). 
A new update came out last week so put that on if you get it. 
Also ask for the security code if activated and changed!
