Many commercials call for overcranking or undercranking. The 2700 is rated at 640 ASA, 3000 is around 500 ASA. 3000 doesn't do 720P, power consumption is a bit higher. Film-Rec goes up to 600% dynamic range with the 2700, 500% with the 3000. There are 3000's available for $20K or so, including viewfinder, so it's a lot of camera for the money.
I bought the 2700 because of its flexibility, but the 3000 is a very good choice and used value. I don't believe the 5 year warranty is transferable, however.
