I have Baywatch vinyl doors on my IBAs. They have some neat features like integrated counterbalance, encoder positioning(no lobe/micro switches to adjust) and nice control systems. Slow close for the last 12-18" seems to work very well on a vinyl door vs an abrupt stop like some others I have had in the past.
I have not personally owned Airlift but have worked with them a some other washes. What I know of them they would be my choice second to Baywatch.
