That's a fairly flawed assessment of ebay.

Before i buy from certain sellers, I always go for the "buy it now" option, and compare the price and shipping, and shipping location, also user ratings obviously.

Those sites you listed above have regular prices, and charge tax, which is why i go for ebay sometimes, especially for insignificant things like memory modules.

So if you get screwed on ebay, it's probably due to your own lack of research on the seller.
