[The Mangler]

Well, sucks that it's broken. From the pics of your's that I've seen, I'd say it did pretty good. Maybe you can fix it. Or if it's cheap enough, just replace it.

For the broken knobs you could always wrap tape around the screw, or run a wing-nut on the end and stake it. Wouldnt look too pretty, but it would work. As far as the other broken parts, replacement might be the only option.
