Expando drums and nova wheels are very different products. the first is a rubber wheel that is designed to use interchangeable belts of various grits. The second is a wheel that has a specific grit diamond coating over a flexible backing. 8" expando drums run about 75 bucks, 8" novas are about $160.

what you need to know? Like Don said expandos will take different grit belts. You can use Silicon Oxide (cheap and fast wearing) Diamond (expensive and slow wearing) and Aluiminum Oxide (mid priced and limited selection of grit sizes- also very mixed results).
