My tool kit is a mixture of both Snap on and Mac along with a few odd ball things inc a set of adjustables from a 1920's Bently (the best fitting tool for one of the jobs I have to do lol)
Dont buy alot of Snap on now due to my local dealer being a twat. Alot of the stuff the two main brands sell are made by the same people anyways but the warrantys between snap-on and mac are different in some cases. i recently bought a new tap and die set off Mac to which they give a life time warranty on breakages, which is honoured as I broke one being ham fisted....Snap-on dont offer a warranty on that set.
My tool box, as this seems to be a sub topic sausage fight

It stands around 6'4" to give a size idea. Need some side cabs but not availble yet
