So, I'm trying to sell my phantom, and the question of the keycaps has come up. They're from the same board as donated the vintage black switches
http://i.imgur.com/F6SHOra.jpgand I'm curious how much to add, or subtract if the offer is excluding, or including doubleshots as-pictures Orange arrow keys are pad printed, not from the donor kbd, and it's likely to stay that way unless I hear otherwise. Also, "fancy" keys such as F16 and "Send" I'm keeping because reasons, and the profile of some of the keys I'm using doesn't quite match the phantom layout.
So, as-pictured, what do you think I should offer to add/subtract from the otherwise working phantom? What do ancient doubleshots go for these days?
