My ebay ID is "medessec2012". Big surprise. lol.
I sell a variety of electronics that I just have laying around... but I also sell Thinkpads that I have fixed up.
As for your post Daz- ebay isn't all that bad, you just gotta be smart and think before you buy. Me and my dad started using ebay when I was 13, and we made a lot of stupid purchases, and overlooked auction descriptions, for example, looking at the picture and seeing a laptop lid, and thinking it's a whole laptop.
But most of the time-sellers aren't conmen, if you receive an item and something's wrong with it, just contact the seller through ebay, and the seller will usually be more than welcome to compensate you or assist in returning the item. For example, I bought a Thinkpad G40, and when I received it, the screen turned out to be broken, and the auction described the screen as working. I contacted the seller, and without even asking me for a picture or proof that the screen was actually bust, he credited me $20 through PayPal to buy a replacement.
The best thing to do with ebay is usually to stick with sellers that have a ton of positive feedback, look for the colored stars next to their name on the item page, and the number of feedback reports they've received, as well as the percentage. Ebay also badges their prime sellers with "Top-Rated Seller", so you can easily make out which sellers are best to buy from. One thing to avoid is vague auctions; ones with little information or no picture. Although sometimes they can be a fantastic deal, it's pretty much bordering on a gamble.
