http://www.dealextreme.com/details.dx/sku.11457 DealExtreme, almost always on the ball, is now offering the new 'N5 Revolution' MicroSD-based flashcard for $31.16. While there are other cards cheaper, this is a dollar and a half lower than the R4 when they last stocked it(the N5 seems to be an R4 clone with a few extra features like microSDHC support, for those uninformed). It's also the cheapest MicroSD flashcard currently in stock, as well. With little known info available, it's probably wise to save your money. This is the first well-known site I've seen with this in stock, so I figured it worth posting. If I put any wrong info down(which I'm sure I did), please correct me.
