Anybody any experience of the Marantz PMD660...??

http://www.solidstatesound.co.uk/marantz_pmd660.htm

I'm toying with the idea of mooching about (next year, probably) with a view
to grabbing 'naturally occuring sounds' - up to very loud, close-up WW2
aircraft engines, possibly. Are these gadgets up to it, or are they really
only close-range voice recorders?

I'm kinda dismissing the Edirol, Nagra and Maycom options on the same page,
but the Fostex looks interesting...??

And why sodding CF cards - is there a particular reason...??

TIA (if any....)
