I replace my tool box last year. I went from a conventional box to a rigid shell tool-case. I checked out RS, Maplins and any others I could find and found Europart do one, part number 55-SE-34. It’s made by Hepco & Becker and is the Budget case. The tool panels inside are made specifically for Europart so if you can put up with the gaudy Blue with yellow trim (check out the special models section on there website http://www.hepco-becker.de/werkzeugkoffer_eng/frameset.php)) it’s not a bad tool case.
I’m not sure I would get a tool kit with the tools complete; you will probably end up with quite a few tools that are not used and still have to buy others that are not provided.
