Over time, some of my worst experiences have come from sellers who are widely regarded as demi-gods on the pen boards, including here. Some have gotten much too content with their undeserved (or no longer deserved) reputations and expect you to accept whatever they send you no matter how divergent it is from their over inflated grade. And, don't dare ask them any questions, they'll tell you they are too busy to answer and suggest you "take it or leave it." I know it is not just me because I find in those quiet 1:1 conversations it often comes out that others have had the same awful experience with them.
On the other hand, I have been many times thrilled and delighted by the terrific purchases I have made from sellers virtually unknown to the pen world. Yes, their descriptions and pictures were sometimes deficient but they were always happy to provide whatever was requested. They just didn't know what to show or describe.
And, of course, I've had great deals with stellar sellers and bad deals with unknowns, too. The whole gamut.
In the end, it is always "Caveat Emptor" or buyer beware. Ask all the questions you need to get all the answers you want. It is said that when you buy a pen, you should always buy the seller, too. Do all you can to get to know the seller and pay attention to your gut. The way they answer your questions (or don't) is a good way to get a feel for them. In the end, there is no seller who has any pen whom I would buy from if I did not have confidence in them. And, reputation alone is not enough to make me confident.
