I'd never been to Mangaya, but I just visited them out of 
curiousity....

So, does anyone know just how common key-master setups from
AIC are? I have two, only from El Hazard OAV1, but I'd 
never seen one from Tenchi Muyo before (which certainly 
wouldn't explain the 800USD price tags on the specific 
Ryokos). How much of a differential would you/have you 
paid on them?
