After an hour of searching for a r4i flash cart, I finally narrowed down my search with this sites recommended site list. I went to the realhotstuff.com and found two R4i with the same price. The R4i Gold and the R4i SDHC. What do you guys think I should get? I also found a R4i card in the site www.consolesource.com. I'm gonna be buying in bulk so buying my R4i there would save me 3 dollars plus it has free shipping. Should I trust it? I never seen a site call it a "backup" card before.
