Drives are cheap, 40 giggers are $140. The size of the empeg isn't an issue, it's the empeg itself. Get into simple economics - supply versus demand and you have the price. I wish I would have ordered a space 10 gigger when they were $199, but I have been more than happy with my single one with tuner (that I don't use too much anyway).

Should my empeg die I will likely go with some solution that uses a hard drive like a cd-changer. It's not quite as cool or flexible as the empeg but it still serves the primary purpose - my listening pleasure in my jeep.
