Ebay is not filled with fakes. I have used Ebay to acquire some discontinued pieces and have had great experiences. Personally, I don't understand why people buy things that are readily available at the store on Ebay. It's beyond me. But, having a lot of knowledge in LV is key to buying on Ebay.
As far as the prices, I think that is really up to the seller to determine how much they want to sell it for. If you don't like the price-don't buy it. I bought a brand new Graffiti Speedy on Ebay for 2k. It was pricey but I could afford it and I really wanted the bag. So, you might think the price is too high but, not others.
And, no I am not a seller. I am a buyer! : )
