Up here in sunny 'straya the Model Engineering exhibitions are few and far between. The retail shops selling stuff are also few and far between, and they mainly sell the same sort of stuff. So if you don't buy stuff online, you probably don't buy much at all.
If you want, lets say some decent drills, decent files, decent taps/dies etc, it's pretty much obligatory to carefully select your seller, hold your breath and dive in, buying "name" brands.
You guys with a choice of shows to go to don't know how lucky you are.
Oh and by the way, before you start complaining that such and such an exhibition is a 2 hour drive away, so you can't go as often as you would like. Melbourne is a 8 or 9 hour drive, and Sydney is a 2 day drive from my humble abode, Perth is 3 to 4 days drive away
