I do not know if you are a member of any LR lists and forums. There are good ones on the internet and from the ones I am involved in I can tell you that they will help you very much.
Sandvik tools are very good professional tools. They are made in Sweden. (My wife used to work in a Swedish company competing Sandvik <img src="images/graemlins/smile.gif" alt="" />) I have seen them sold in UK.
They also have sets for different purposes. Not only mechanical they also produce other tools like saws, shovels etc. Maybe a good bargin maybe obtained if you buy a whole set.
IMHO never go for Draper, Stanley or alike. Nice shiny tools:)
Good luck with your trip.
