I stopped in the local GC this afternoon, and found one of these:
Mine wasn't that much. Would you believe $25, and in much better shape? Just missing the rubber feet and screws.
It's a pretty cool phaser, supposedly related to the small stone. There's an extremely wide range of sweep speeds, and the recycle knob adds swoosh. Dime 'em both and you get atonal ray-gun sounds.
I had an extra stomp switch lying around, so I modded it for true bypass. Something cool to have lying around the house, even if I don't use it that much.
