Well, while at the local Goodwill Junk Store, everything under 7 pounds is $1.50 and over is well just $5.00, I found a PanaVice with a  vacuum base (model 380) with a set of PCB arms. Now the picture is from the internet. Mine is much worse for ware, the center bar is badly rusted even though the arms move freely. And at this point I have my doubts about the vacuum pad as well.  But since is was only 3 pounds my cost was $4.50 not bad for about a 90 dollar piece of kit.
