Doesnt matter which kind of ACEKARD you will buy.
but... it is recommended to buy AK2i version instead of that one you post... (AK2.1 has troubles and since start this year, they have BAD BATCH, so you cant play many games on it)
btw. both versions works with almost all games - if you use AKAIO system on them...
I don't know anything about that website. But you could get one from 0shippingzone.com they ship everywhere for free. You could also buy it from Gamekool.com and also get free shipping and I think its a little cheaper in Gamekool.com
EDIT: Do not buy from Dealextreme because AKAIO 1.6 won't work on those Acekards for some reason.
I'm also buying an Acekard 2i, but not to sure where to order one from as of yet... Kickgaming or Gamekool..
EDIT: Lyuse I don't think you should order from Gamekool, I've decided not to because they are here on the Black List: http://gbatemp.net/index.php?showtopic=81021
