Some will have the discussion on here about these plugs. I'm now in touch with the Kyoto Tool Company in Japan who make them. They've asked me to ascertain how many I want and then they will give me a price inc shipping. Their list price is around £17.50 and clearly I have no idea how much shipping, taxes etc will be at this stage. If it looks good I plan to take 50% non returnable deposits up front before ordering to ensure I'm not out of pocket. I won't be making a profit on these unless someone backs out in which case I'll sell the socket for the best price I can get. So, who is interested? I can go back with numbers and see what they say. Let me know asap please.
