I have the American Harvest Snackmaster Express. It has the fan and element on the top so the mess is easy to clean. My book says it expands up to 12 trays. My book also says top rack dishwasher safe, but I put them in the bottom and make sure I catch it before the drying cycle. It was $40 or $50 at Wal-Mart last fall and it came with some extra goodies.
