@JoeyQ: I believe the blue legend TA caps are dyesub, yes. They're not duble-shot at any rate. Is there any way of telling 100% without damaging a keycap?
Yes, being in Germany certainly helps with yummy Cherry finds!
As for what I'll do with them - I don't care for IBMs very much so will just sell those as they are. Other than that, I'm thinking of buying an ultrasonic cleaner and giving them all a nice clean, harvesting some caps for my other boards and again selling or trading a few - still looking for a nice blue Alps board...
