In defense of the Doctor,
I bought another of his Cybervision 64's (his other board he offered a couple of month's ago)
and he was most pleasant in the transaction, and
packed it well and offered software via download too.
Ganging up on him seems not too fair either.
There are too many thiefs even on Ebay that
take money and deliver zero.
PPC accelerators seem the biggest inflated prices.
I found his board in new condition.
