I know a company in holland who have two used zodiac 650 pro open's for sale. (I just bought a 650 Pro Open from them)
The company is called: Bootcentrumhoorn
There email adres is: email@example.com
There phone number is +31 229236060
I can recommend them for there service and attention.
During X-mas they are closed. (exept for my test raid) But you could send them a e-mail
