OK, I can't help going back and looking at these.
Have you noticed... he's lowered his price by $5.00? Now $84, shipped, for 4, so $21 each.
What do you get?
* 44 Cherry brown switches (less than $0.50 each if you tossed everything else)
* 38 less than stellar keycaps, but where else can you get two 2x2U caps like that? (Again, if you tossed everything else, about $0.55 each )
* 1/2 of the boards have front legends for "E" to "Z". Abba need not apply.
* Mounting Plate
* Some odd interface, possibly something like serial I/O, but who knows.
* Case.
* The knob on the back indicates settable volume for the buzzer/alarm.
You could strip the controller out of it, wire a micro into the matrix with TMK or QMK software and gave a fun, if not great, macro board.
How about I offer him $30+$34 shipping. Makes them $16 each. I'll re-box and send to you in the US for $16+my shipping costs.
Do I have 3 takers?
