I was pondering for a while over the choice of guitar support. Ergoplay-type devices initially felt like first choice (no practical experience, just from reading reviews), but there was one key aspect to address: I've got a classical and two acoustics guitars. The idea that I would be regularly fiddling with suction cups back and forth didn't quite resonate with me. So I went for a Dynarette High (I'm relatively tall, 182 cm). What can I say? It's simple, it's nicely manufactured - I really have nothing to complain about, and it just works to my full satisfaction. If I need to switch guitars - that's done in a blink of the eye. Really convenient. And there's nothing to break, nothing to replace... I recommend it without hesitation.
