I'm posting this here only for the fact that those interested in the Aple 1/Replica 1 might be interested in this...
Nuts & Volts magazine (August 2006) just ran a construction article for a "replica" of the COSMAC Elf computer. Sounds like quite the project to include follow on interfaces to include a video display and a disk storage device.
The full kit minus the toggle switch front panel is about $250 and the prices go down from there.

So..Tom...Vince.... when are you two going to submit the Replica 1 to Nuts & Volts?
