Thanks for all of the kind words.
The thing actually looked pretty tame, I picked it up VERY gently with my bare hands and placed it on a piece of paper to get the shots. Looks much nastier in macro!
I think that I messed up with this one though

When I took the first couple of shots of him I noticed all of this cobweb stuff around his front legs so I removed it very carefully and what I couldn't get off I cloned out in
PS.
DOH DOH DOH DOH DOH
I guess that was his net which he was waiting to throw at me.
Thanks for the ID Rel. We have LOTS of weird spiders here at the moment I think I might try and capture a few more before I break into the Pidgeons Pest Control bulk store.
