I would have to agree with Dave, there is no point in spending a huge amount of money on equipment which is far better than you need. As long as the tool suits the type of work you do and you are not working 24/7, good enough is good enough. I have spanners I bought many years ago, not top-of-the-range, which I,m still using. I also have some Aldi and Lidl sets which are quite good enough for my needs. OK, some stuff needs to be good, but not all, otherwise very few of us would have anything, due to cost.
