I have an old Mary Proctor Double Flip, which has a built in 14" tall minder with a plug. I use it occasionally, but I find the 'eye' (1" in diameter) that you thread the cord thru to be a little restrictive. when I thread the cord thru that it sometimes hangs up. When I do use it, I use a loop of seam binding to make a larger guide. I got the board at a garage sale, and I'm a bit leery of the electric hookup, so I plug the iron into the wall.
