I use 1084s because its what I have for my A4000. I have an indivision ECS for my A500, so it goes on a modern monitor.
I hate the 1084s. I have two of them. Cooked one the other day. The second one goes yellow/green if I don't spank it. As soon as I get an indivision for the A4000 they're going away to someone who cares about those sorts of things.
