I am British and live in the UK, I have used Dan and his shipping costs were crazy low…. But then they would have been small boxes.
There was another guy in the UK called Red Onion solutions…. But I don't think he is around any more and to be honest he was probably more expensive than Dan.. Even after factoring in taxes and shipping.
I would perhaps ask over at The Gear Page forum, in the Effects, pedals, strings and things section to see if anyone else knows of any other European dudes who may be able to help.
