Considering that the price is 10.000 with mount + the minimum Red accessories 5000, at 15.000-18.000 you have a full set.
You need to factor in memory cards (REDMAGs) too. The 64 GB SSD included in the bundle will only get you about 30 minutes of footage, & will take 45 minutes to backup to two drives over Firewire 800. Want to shoot all day without downloading...add $7k.
Handheld outdoors in bright Sun...add $3200 for the Bomb EVF. More if you want to actually attach it to the camera.
Cage? Handles? Shoulder rig?
The Scarlet's a deal, but I'd be factoring $25-30 without lenses.
