Not many people have had great results in the hobby from ebay pixels from what i've seen. Most you find will source directly form vendors such as Ray Wu or Paul Zhang, and in the US you have the likes of RGB Man and Wired Watts (who I assume just resell from the china suppliers anyway)
At least then you have someone you can contact if you have any issues as most times these vendors will offer replacement for free for any faulty products. Good luck getting that from an ebay vendor! But no harm in asking the ebay seller for some assistance, worst they'll say is no/go away.
