Under $1000 - a power cage, a bench, an olympic weightlifting bar and a few hundred pounds of weight plates.

I never liked to go to the gym and having the essential tools at home have been the first time I've stuck with it. I've increased my strength substantially, lowered my body fat, and I generally have a better mental state with regular exercise incorporated into my weekly routine. It does require a good bit of space though.
