I have two of the classic darkroom timers. The first one is a Time-O-Lite clone by Simmons Omega, and it's old enough that it only supports 2-prong plugs. The second is the real deal, and newer so it has 3-prong support. The actual Time-O-Lite even comes with original box and instructions.

$10 each plus $10 shipping in the US. Besides the power needs being different outside the US, these are heavy enough to be expensive to ship outside the US, so I'm going to assume only US residents are going to want them. If that's not the case, let's talk...
