It's actually much less. I'd fear buying that Scarlet. He doesn't know anything really. You can't transfer your RED Armor warranty. BE CAREFUL! If it were me I'd only buy a Scarlet through RU, or RED.com
As far as size, they're much bigger, and heavier I'd say. The body itself is about 5lbs, and 5 inches tall, 4 inches long, and 4 inches wide. Thats a guesstimate. With a sidehandle, add 1lb. Another 1lb with the Touchscreen. Once you get a V-mount adapter or battery on there, unless you want to use the 30 minute lasting Red Volt's, you add another 2-3 lbs and 3-4 inches.
My run and gun set up with a lens weighs in at about 9-10lbs.
Transfer fee is also cheaper now. It's about $500. I know because i'm selling mine.
