Em, better not post reseller site, but I have bought this R4i-gold card in modchipsupplier.com You may check this, but shoptemp is a better place to find what you want
Maybe you can try to format your card and then put the kernel into it and update. Last time my r4 broke I tried this and it worked, maybe you should take a try but I can not guarantee that it can works in your case.
@Xdqwerty, to answer your question, they're a fusion Brit-pop/J-pop/electronic band with a woman vocalist. Flamingo is hands down their best known song but they've got a ton of other really good songs
