I started off with afew cheap tools from the £1 shop and then just developed my tools/etc from experience.....
Im one of those people who would rather carry excess, than have to retire from a meeting cos I didnt pack something
Oh, and add "shock stand" and "car stand" to that list
If you want to be gash (which I am) just ream 4 x 15mm(ish) holes into the lid from a big empty can of brake cleaner/etc and use that as your stand..works a treat
