I found the elewelt site (it's not .de anymore it's .net) when I was looking for card readers last month. I ordered a SKY3DS+ card a month ago and got it yesterday in the mail.
You can get to the site but some links don't work. I don't want to promote the site, but I got what I ordered and the chat works: I tried it this morning. So just a positive review.
Thing is I don't need the SKY3DS+ card anymore so I asked for a return address : I was bummed because the return address is in China and shipping there would cost me too much!
