Yeah, I had a not-great experience with one 
seller and no longer bid on that seller's 
auctions.  Even if someone really spectacular 
comes up, I'd be concerned about the cel ever 
showing up!  I have enough stress in my life. :)  
Fortunately there is only one seller I've put in 
my blacklist, so there are many other very nice 
people to deal with out there and it hasn't put a 
crimp in my collecting.
