My tools were acquired over a long period of time and the first batch could be characterized as "reasonable" or "useful." These included a circular saw, a jigsaw (that I just discarded in favor of a new Bosch), a power miter box and an old Craftsman flex-drive table saw. These allowed me to do "reasonable" and "useful" work.
My first "good" tool was actually several upgrades for the table saw that included a zero-clearance insert, an after-market fence, a carbide-tipped blade, a stacked dado set, an after-market miter gauge and an analog dial indicator for machine setups. These really upgraded my capabilities and allowed me to make really straight, square, repeatable and accurate cuts.
But maybe the "best" tool in my stable was my TV that allowed me to watch 20 years of Norm Abram. I learned a LOT from Norm...as I'm sure did many woodworkers.
