Hi Sally.
I buy loads of stuff of e-bay and there's quite a lot of 'technology' cheap from Hong Kong and China. I'd suggest 3 points: 1 - check the seller's feedback carefully. Don't just look at their score, but actually read the feedback - particularly that which is from people with a decent feedback score themselves. 2 - Look at the cost of the whole deal, including postage and insurance. Often the basic auction price can be really low but the seller makes their profit on the postage. 3 - Use a secure payment method, like PayPal, and if you run into problems make sure you start taking the right action in good time ! There are a couple of sellers in China which I use frequently and always feel I've got a good deal. One other, which I used once, never sent the goods but I got a full refund from PayPal. Buyer beware - but use e-bay carefully and it can be great ! Hope this helps.
