One of the review pics on this one seems to be exactly what you’re looking for. And it’s from monoprice no less.

I’d recommend mounting this to a stud or building some kind of reinforcement if that doesn’t line up for you.

Wall anchors like toggle bolts are probably fine if you use enough of them.
