I bought the Gibraltar 9707 xb hi-hat stand to have a second hi-hat on my drum kit, and I attached it to the china stand on my right. It is a well made, sturdy hi-hat stand, with a ton of adjustments, Gibraltar quality. Very stable, I already gigged twice and used in in a couple of rehearsals and it is very stable, you can totally rely on it.
It`s not a very cheap piece of gear, buy you have to pay for quality isn`t it?
