You never want to dropship from China. You purchase goods in bulk from China (wholesale pricing), not dropship.
Most people are using Amazon to dropship to their Ebay account. That is the most reliable way of finding a dropshipper without paying for retail pricing. A drop shipper typically charges you fees, has you sign a contract, and you are limited to only selling for them. It's not worth it IMHO.
Why have your hands tied behind your back when all the profits can be found in plain sight with a little searching on Google and Amazon.
