Ebay is not what it used to be, but the prices are still the best. You just have to be ebay-savvy, not in a hurry, and complete in the scrutinizing of the potential seller.
Good advice. Also see if you can use BIN/Live Cashback where you can to reduce costs. (
see this thread).
eBay in general is reliable, it's just that some things are almost inevitably fake. One should exercise
extreme caution buying certain categories of things on eBay (designer clothes, shoes, or accessories, flash memory cards or memory modules, etc), but most other things are safe as long as you don't choose a disreputable seller. Stick with people who have a lot of feedback (and well over 99% positive, or else look at why the negatives were foisted), have been on eBay for a good amount of time, etc, and you'll be fine.
I've bought several things there recently, and I did have one bad egg seller. I paid her immediately for a BIN Logitech Mediaboard Pro, waited patiently for two weeks, and then e-mailed her politely asking for tracking / shipping information. Whereupon, she responded to me that she had trouble with
another seller, claimed her account was frozen (although this certainly happened after I paid her), and that she had not shipped anything to me, would not ship anything to me, and could not specify a timeframe to give me a refund. So I had to use a dispute against her, and it took 10 additional days for dispute resolution, but I finally did get my refund in full.
