Amigas in the attic...

[jj]

Since you're in the UK, you might be close to Amigakit. They have many Amiga items brand new and, although they usually charge a good price for them, they are reliable. They also have paid technicians in their employ to help you out. I've been dealing with them for about five years and they have known how to help me, especially with expanding and modernizing my classic Amiga machines.
 
Good luck and welcome back.

Depends how close he lives to Cardiff
