Again, thank you for your input Jon. 
I've looked these bikes up on the web... not really what I want and too new for my budget but I appreciate the suggestions. 
I don't compete, but like to ride in out-of-the-way places. I want a slow, torquey bike for ambling around, disturbing walkers and shepherds ( yes, really ) as little as possible. I ride, I stop and enjoy the scenery, I ride some more etc. And I'd like to learn new skills albeit at my own pace, which I don't think I'll do on a faster trail/MX bike. I'm pretty sure it's an older trials bike that I need ( perhaps marginally geared up ). 
I do have a friend with an old Bultaco 350 Sherpa who I may ride with on occasion but on the whole I ride alone. 
Just trying to give a better picture of my desired use of my intended "new" bike. 
All thoughts are appreciated though, which is why I made this post. 
Thank you, 
Nick.
