anyone know how much the HD100 rents for?

Hollywood Studio Rentals have a good rate...

But on average I found its about $300 for the camera... but you can get it cheaper... just depends on where you are...

so far i've found $200 and $250 for camera and tripod.

In Vancouver, BC, one dealer I spoke with rents it for $275/day or $1,100/week (Canadian)
