HankronThe following are what I want/expect from people I regularly buy from:
1) Authenticity
2) Strong understanding of what they are selling. The quality of the item in context to others in the genre, historical context, etc. This is usually expressed in the description of the item or, otherwise, upon communication with the seller. For example, if the seller says this is a rare example of X, you don't want to find out a month later that there are tons of them around.
3) Accuracy of physical condition. Not just condition, but general appearance (I'm not a condition freak). If the image is said to by crystal clear I want it to be crystal clear. If it's supposed to have brilliant colors I want brilliant colors. I bid on that crystal clear image and brilliant colors, and I want 'em. If the seller says there's a crease or the image is off, don't worry I will be expecting a crease and an off image.
4) Honesty and sincerity.
5) Getting the item and a bit of friendliness. I'm less worried about time or shipping cost, as long as I know I will get it well packaged.
In short, for a good seller, what the seller says it is is what the buyer gets. There are a number of sellers who fit the bill, both big auction houses and individual collectors, and these are the people I will buy from.
