Yep have never gotten a gym membership, bought my own stuff ages and have never looked back! Got an adjustable incline/decline bench with lat pulldown and leg curl/extension attachment and squat rack sort of, a separate cable machine (lat pulldown, machine chest press etc), barbell, EZ curl bar, dumbbells, heaps of weight plates, resistance bands, chin up bar, portable dip bars, and a heavy bag hanging on its own stand.
The main stuff (bench, barbells etc) have lasted me almost 20 years, how's that for value! Haven't had to replace anything.
People have said to me I must be really disciplined to train at home, and I just think it's so much easier to be honest. I enjoy it so much that it was never something I felt I had to force myself to do, and a habit I built that nowadays it's just something I do without question or effort.
