Two questions 1. Does that guy have kids? 2. If yes, where do they play in the garden? Its a massive eye soar for what it is
3 x 3 metre scaffold poles, hire a fence pole driller, 2 plastic sleeves and a bag of ready mix and either 2 x 90 degree bends or a hacksaw and a welder. Removable bag stand that'll hang 2 bags and have space if you want to fix a speedball using u-bolts on the uprights. Tin of paint - easily removable & would last for years. You could even pad the uprights for added sexiness
Done that myself but they're often quite cheaply made now. Also probably as much as buying a bag stand.
