Derek,
I would contend it is also the dealers/retailers that greatly influence this issue. As far as the UK markets go, I believe it is more of the stature of several tool retailers that interact with their customers much the same as LV & LN (and routinely sell the knock-offs) that has cause the widespread acceptance of those tools in that country. Another reason, is the fact there are many more workmen in the UK using handtools in their profession as compared to other countries, such as the US. I believe Kees is correct in the message he stated, as far as a need for decent midrange tools.
