I’m a tech freak and I do enjoy using what I buy to it’s fullest. The Micro SD card slot in my Sansa is just one of those things that irks me. . . I really want to fill that slot up with something, if anything. The cards I found around Sandisk’s line were rediculously expansive. . . Ebay I just don’t trust. I did get into this one site a while ago called Newegg which did an excellent job. A friend of mine was a support agent there for a few years. Anyways, this 8 gig card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208463 ) is just a mere $16.65 compared to sandisk’s $100.00 + card. I’m not trying to advertise, but advise people like me that memory expansion is affordable.
