I come upon them often. I'll just give it to you when I pick up one, I have a pile of broken Beckers sitting to my left.
I'd go for a 754-780 model if you choose to do this, they're better than that old 611 or 612 model. I have three bad 1480s, a bum 754, a bad 1432, hrmmm... maybe a 612 laying about too.
