I would have to disagree with you re your
comment on how cel buyers are "more mature and
responsible than many other catagories".  In my
experience it is the cel buyers who, more often
than not, back out of their bids, never send payment,
respond or conveniently "forget" to send payment at all.
The "I forgot to" people usually play this right
around convention time or after a BIG Taro update.
They then post here announcing their finds, or that
they have to pay Taro "first", even though the auctions
predated the new purchases. Very irresponsible and
unprofessional and more so in the cel auctions than
any others.
