I must say ScanDisk Sansa Fuze is pure goodness. I paid $50 for a 4GB internal memory Sansa Fuze it has similar functionality to an ipod at a fraction of the cost. And here is the real kicker. It accepts micro sdhc cards! So, if I run out of 4GB of internal memory I can pop in a 2, 4, 8, 16 or 32GB micro sdhc card and continue to increase my music capacity. The mechanical wheel moves smoothly. The whole unit has a nice size and weight to it. And the screen is crisp and clear. I could not ask for a better unit.
