So where are the good deals on MicroSD cards? I'm interested in at least Class4. What are you using with your GTabs?

http://www.newegg.com/Product/Product.aspx?Item=N82E16820208475Keep in mind that the class is based off WRITE speeds. I have a class 10 in my Vibrant, but only a class 2 in my Tab. That is because I tend to change what I carry on my phone more often than my tablet and thus it is noticeable. But if you are just going to load up 4 gigs of music and 8 gigs of movies and never change it, go with a cheap card.
