Looking for a good cheap 8GB Memory Stick for my PSP...

I need a good cheap 8GB MSPD for my PSP because i'm out of space on my 4GB. I live in Canada, just to let you know. Anywhere around 40$ and down is appreciated.

Amazon, I find, is extremely cheap when it comes to MSs.

I've seen a Sony Mark 2 8GB selling from Amazon for 38 dollars some days, sometimes 36, one day it was 32, officially from their warehouse so it's legit (I've been tracking it because I'm looking into getting one as well). If you find any deals remember to make sure they're legit sellers, as many people like to sell fake memory sticks online.

I buy all my memory cardsfrom dealextreme.com.
