Anyone that says ebay intakes are crap is stupid. Its just a peice of filter with a tube, thats all there is too it. I wouldn't be suprised if plain old PVC piping does just as good as a job as any AEM/K&N/Injen etc. intake does. Get the ebay one, I've got one and it does a fine job at what it is. Why not get the ebay intake, toss the filter, and buy a brand name filter? It will still save you a lot of money over the full name brand intake.
