Read the review, but the tech is solid. 32′ cable will cost $300 and 100′ about $650. That should cover most needs.
The cheapest 128GB CF card I could find is the Komputer Bay card, although I am not sure I would trust this.
That would make a 640GB Raid 0 for about $853.
I think for that kind of money, I would rather have the Promise J2.
This is way overdone, but I think it shows that the iPhone as a video tool is completely appropriate for certain situations.
Just ordered one on these. Watch for a hands-on report this week!
A great article that breaks down the major functional features of FCPX 10.1
A must read.
