I use a rotisserie jig to hold circuit boards, is nice. Has a spring to move in and out to hold the board, flips around, and holds position. I would show a picture of it here, except the forum won't allow me to insert pictures (with ease). I bought it at a flea market for like $5.00 and had no idea what it was until I looked it up when I got home. It's old and indestructible. They are rare, I've never seen one for sale on any modern electric tool supply.
