What about http://www.chipper.se then?
Good Swedish site, also shipping international.
Althougth they only have M3:s, but IMHO that's the best card around.
@K3Nv2 I got some cheapies at wallys, that are pretty good, already have lost a few expensive ones (one falls out and gone, can't find) while cutting grass so bought some cheap ones, and of course never lose these cheap ones. (Cheap meaning only $35, compared to air buds which I only have 1 of 2 now)
