Saw this on Ebay a couple of weeks ago, it had just been listed so I made the seller a stupidly low offer of £45, which he accepted, I couldn't believe it. 
To cut a long story short it arrived and was in mint condition, I say was because very bad packing led to both ends being damaged, one end badly smashed.
The following pictures are after repairs to the damage and repainting, there is a couple of posts on Boomboxery showing all the damage and repairs.
I am very pleased the the repairs and the rare M7830 is now back to it's former glory. The first picture is the badly damaged end.
