OT: Consumer HD camcorder compatible with FCP 6

Our project involves some experiments in production and we won't be using
Varicams or HDCAMs for this idea. I've been looking around and see two camcorders
that are reviewed well, the Sony HDR-SR11 (AVCHD to hard disk)
and the Canon HF100 (AVCHD to SD card). Both have USB2 and HDMI out.
Will FCP work with these cameras for capturing or transferring?

If FCP can capture these formats natively, then we can work with laptops and
without video cards, at least for roughcuts.

Or must I use a Mac Pro and a Blackmagic card that has HDMI in?
They have a card for around $350.

Will FCP work with USB for control, (not for video in) ?
The Blackmagic HDMI card does not control the camcorder
and they suggest firewire for control, but these camcorders
do not have firewire out. OR does FCP work with USB video/audio/control in
like it does with firewire?

I see the AJA's HD Io has HDMI in and out, but that's $3k, and not
in the right league for this kind of testing and budget.

Thanks for any help.
