The two best things I ever added to my brewing repertoire were the use of a swamp cooler for temp control, and proper water treatment for my AG mashes. There are no words to describe how much these two simple, cheap changes in my technique have improved my beer.
Other wonderful items I added to my arsenal (not all necessarily cheap) were my refractometer, starter stir plate, and of course my kegging setup.
If I have one regret, it would be buying a 1 liter flask for starters. My minimum starter size now is about 1.2 liters, so my small flask is just collecting dust. But I suppose I will use it if I ever decide to cultivate yeast from bottle dregs.
