Rob,
You might check out ebay before committing to fixing that one. Also surplus machinery sales dealers will occasionally have these kinds of items for fairly low cost.

I've used mine for many things, but I think it's highly dependent on what cleaning fluid is used as to how effective it is. It's not the end all to cleaning tasks. But on occasion it helps. The really gummed up stuff is best and most quickly removed with a stiff brush and good solvent.
