I used to think the exact same thing you did. Until I got into bed with these people, and they ended up fucking me over for a whole lot more than an R4 cartridge or two. Take sonic in the other thread, who ordered from a seller on Aliexpress. Now his stuff is broken after two days of use.
EDIT: I'm not saying, by any means that all unofficial resellers are bad. Hell, I know a few that are actually more reliable than official ones. But the resellers are seriously there for a reason. I'm not going to stop you or anybody from purchasing a Gateway elsewhere, but you really do not get any right to complain if your unit ends up not arriving, is faulty, etc., because I have clearly warned you and a lot of other people who have unfortunately chosen not to listen to my advice. And after five or six years dealing with the Chinese, I will most likely not fuck you over. I'm merely here to help people make the right choice, even if that choice is something you do not like or want to see.
