Buying items from ebay?

[LacusClyne]

i had been wanting to go up to ebay to find some ayu singles. but i'm afraid of meeting dishonest people. can anyone list those good sellers that you had encountered with? and those bad sellers too.

and maybe a little guide on how to avoid fake products, there should be other members who need this too.
in my case, i thought it should be better if the (japan version) that the sellers claimed comes with a picture of the whole cd case, with the obi, booklet, both side of the cd.
and it's the best to buy from those at least 99.99% positive feedback?
am i right?
