You should contact OGR forum member: "Scrapiron Scher", he has Z4000's up for sale.... I have purchased alot of stuff from him, it's all been in really great condition, well packed and shipped for reasonable charges... I copied and pasted in a line from his current listing.... below that is a link to the listing, but you'll have to copy the URL into your web browser or find him by searching members......
