So I decided to work out at home, what equipment is recommended? I've been going to the gym for about 2 years until 3 months ago when I stopped having time to go. I decided to get some weights and work out at home. 
I was thinking along the lines of an adjustable squat rack with a bench and weights, then two barbells with mini weights. 
I've obviously never done this before, so I'm wondering if there are any brands I should look for or avoid, and if I should buy used or new?
