Also try this link...http://www.tradeframes.co.uk/
I think they are the same people as Fast frames. Fastframes stopped trading for a little while. When I recieved my next order, all the emails, links etc were for tradeframes. Exactly the same packing etc, but came from london, not Norwich.
Interestingly, the receipt was headed as Nielson Bainbridge UK.
Very fast delivery, and reasonable prices aswell.
Hope this helps.
