Just noticed that Sony has a promotion running on the Z1 through September 30:

Sony Business Z1U Starter Package
Receive a dual battery pack, DigitalMaster tape (10 pack) and Vegas 6.0 software rebate by mail following purchase of an HVR-Z1U model Sony HDV Camcorder.

I'm not sure what the details of the "dual battery pack" or "Vegas 6 software rebate" are... maybe someone else has info on these? But at $19/tape that's a nice little perk! :-)
