David,  Can you be more specific as to the whereabouts of the firm that sells the fencing bits.  I went down there today.  Turned right onto the estate off the 340 and went straight on and over the small roundabout.  About 50m up on the left I found a place called Farjardos Amigo run by a Pakistani bloke called Abdul.  They seemed to be fabricating gates and stuff but he didn't have any fencing in stock but said he would ring me with prices tomorrow.  Do you reckon this is the place you mean ?
