If a person has an online gallery, chances are 
good that they are honest. This is because they 
are publicly collecting, and if they want to 
continue collecting, they will most likely avoid 
making unwise choices, such as scamming someone. 
Like someone mentioned, most people come to this 
forum. If word gets out about a person scamming, 
even once, it wouldn't take very long for the 
entire community to find out. (As well as ruin 
this person's collecting reputation for a while). 
Collectors come here not only to show off cels, 
or advertise sales and updates, but to warn 
people about someone, if neccesary. I've seen 
several warnings about bad ebayers on this forum, 
and have found it very helpful. 

Needless to say, you have come to the right place 
to ask this question. Being new is scary, and 
it's always nice to know that there is someone to 
help. 

Even though this community is overall kind and 
helpful, don't let your guard down. There are 
some rare instances where someone will try to 
take advantage of your newbie-ness. The old 
saying: if it sounds to good to be true, it 
probably is. And if you're still unsure, just ask 
someone. With a hobby that so much money and 
sentimental value is involved in, you can't be 
too cautious. 

Welcome to cel collecting! Please check your 
sanity and your wallet at the door :D
