I guess people just seem to loop resellers and scalpers into the same lot oftentimes. I have no problem buying something from someone for a low price and selling it for a higher one. For example, I bought a special edition PSP from Jugo for $100, and it's well worth $200. I used it lightly; it was my first PSP and I had fun with it until I bought another (cheaper) PSP for myself. Now I need to sell it, and one way or another I will be making money off it.
Some people think that's a douchebag move, but hey, I don't have money to throw around like some people.
