The reason people are annoyed by this and giving you a hard time is that it is against the forum rules to post links to auctions. It is not uncommon for people to try to promote their own items here (on ebay, or their own company's webpage, or whatever) while pretending not to be associated with the item. These posters are essentially using the forum as a marketing tool. Occasionally, some person who is new to the forum will actually not catch the deception and purchase an item that isn't a "hot deal" at all. The practice is usually deceptive and frowned upon. Thus, it's forbidden in the rules.
Whether or not the above applies to you, most of us will assume that there's at least a chance that it does. Some people are less tolerant and/or more aggressive towards rules infractions.
It's also not the purpose of this particular forum to ask for advice (as you did in your other thread). It crowds up the boards and makes it difficult to find things. There's a video forum for just that.
