Not counting a home: my favorite purchase has been a good stereo for my home office. Nothing that broke the bank, either - I picked up an older Technics receiver and a pair of Advent Legacy floor-standing speakers for under $200. Now that I stay in the same room 12-16 hours per day, they've been extremely helpful in making things feel less boring and monotonous.
