I have heard mixed things about Gary Coxon - sometimes he tells people he cannot help them and other times he can - depends on how he is feeling at the time.
I once had a problem with my
sage rod that was strangely ticking I phoned him about it and said he had never heard of the problem before - my pal had actually phoned him the previous week with a similar problem so he was just fobbing me off - turned out it was excess wax.
I doubt Coxon wants to know if you buy your rod in the states as he does not earn any commision from it anyway.
