Pete,

It's not 2 or 3 hundred, but for the money, you're hard pressed to beat the EV5u-Pro valve sold by Todd at Dreamworks. Not only does it control the brakes and gear AND gear doors, but it also has a built-in gear safe that will automatically drop your gear if they go below a certain air pressure.

You save time, money, room, and weight.

Oh, it uses two channels....1 for gear and 1 for brakes.
