Also, I have the Phoenix, which offers a much finer speed adjustment than the Speed Box. it's not just an intellectual exercise - I found I could not get the speed perfect using the coarse .1 increment found on the others and needed to go to the finer adjustment to get it dead on.
I like the Phoenix a lot, BTW. But then again, my TT started running very fast for some reason, so I needed an outboard box of some sort.
