That's been my method, there seems to be hundreds if not thousands of them. I select the product/price I want, see if the feedback count is greater the a couple of thousands and satisfaction is greater then 98% and have never had to give out a negative rating. One vendor sent the wrong kind of pot (I bought a dual gang but got a single gang pot), vendor just had me send a picture of what arrived and based on that sent me the correct one. All other buys have been problem free. Not saying the everything I bought turned out to be a wise purchase, sometimes spontaneous buying decisions result in some amount of buyers remorse, but not because of the quality or description of the item offered. About the only rule I try to keep with is that there must be a datasheet or schematic drawing linked or embedded with the listing or special ICs and electronic modules. Don't assume you will get more technical information or assistance then is shown or you may very well end up being disappointed.
My experience is that the Chinese E-bay sellers are very protective of their E-bay feedback rating, much more so as rule then many of the individual state side sellers I've run against.
