Kitsch-Bent is now selling these brand new Smart Cards. Unlike the original (obsolete) 32MB Smart Card, the new (doable the size in a sleek black casing) 64MB Smart Cards are USB supported. This means you just plug it into your PC via mini (b-type) USB cable. These are a great advancement in flashing for musicians who like to have a variety or music apps in there arsenal (i.e LSDJ, MuddyGB, ect) all in one cart.
These carts are for sale now HERE and the sale price wont last long so snag em up before the are gone and become eBay gems.
