Where I find most eBay sellers to be stinkers are in that they are very poor losers. If the list something small like 10 dice for .99$ they then add p&h fees of $12 to cover their loss on the grounds that they can charge handling fees of any amount (not true, eBay has a policy of reasonableness). Another drawback that eBay refuses to deal with claims under $25, and sometimes the internal clock of paypal is screwed up so you end up shelling out up to $24.99 with no recourse. Sellers like sellers everywhere are good, bad and in between. Secret is find one that you can trust and build a relationship. My favorite one for Traveller stuff is a guy who goes by the handle Timmon who will selling some more stuff soon.
