Interesting. Well, depends what the seller wants for it, and what you’d want it for.
I would still pay about $50 shipped (so I’d buy one from a US recycling center, but probably not from Greece), because I’m somewhat interested in comparing all the Alps-mount switches I can find. I’m sure there are other people here or on Deskthority who feel similar, and would be interested in taking pictures and documenting the keyboard, etc. If someone really likes Omron switches, and has some from a different source, this would also probably be among the best hosts for them, with a sturdy case, metal back, etc.
But if you want to find a keyboard to type with all the time, you might not want it.
