Statement in Brent's post, because I could never have thought that to do good and have a large feedback could be a negative thing.

Of course, I also tend to avoid auctions in general where the seller's feedback is too high (say, over 500 or more), because odds are they are doing this as a business, which means in general you are going to get less customer service, and will be lucky to get feedback-- regardless of whether or not you have left it first (in my experience). Nonetheless, if it is an item that I really want or the price is right, I have been known to waive any or all of the above rules .
