Ten keyboards in a box. $60 for each keyboard ...
whatever it is- No guarantee what you'll get:
foam-and-foil,
Alps or maybe one of the rubber domes, perhaps.
- No guarantee that more than two keyboards will have a complete keycap set.
- No guarantee that any keyboard will work.
Not worth it ...
... But do make a note of the seller, and check back in a month or two to see if he has lowered the asking price.
