...it's all about capitalism, kids!  If someone 
wants to pay $200 for a cel that I think is worth 
$20, then more power to 'em!  They'll buy it, I 
won't.  And I'm sure there are many situations 
where it'd be reversed (ie I'D be shelling out 
for something and they'd think I was crazy ^_^;)  
Personally I don't care for people who buy tons 
of junk and try to hock it off on ebay, but lots 
of people do it anyways to make a quick buck.  
It's not illegal, and only a tiny bit immoral 
(after all, it DOES give all of us a chance at 
it, even if it does end up costing a lot more 
than it's worth)
