So, since my last post in august, I got the sony PCM-M10 and can't rave enough about it !!
It's ultra portable, has a otherworldly battery life. I'm using my *second* set of AA batteries since august, and recorded more than 8Gb of material with it at the best quality settings, with (almost always) monitoring and re-listening the recordings sometimes several times - it is just unbelievable !
Sound quality is top notch, it compares easily with or even surpasses my previous korg MR-1, and I can use either the built-in mics (pretty good but very wind-sensitive) or plug directly my self-powered rode NT4, or my binaural in-ears mic (with plug-in power). No need for XLR in my case.
Before buying, I was also tempted by the Tascam DR-100 as well, but the sound samples I found on the net were nowhere close to those from the sony, with a LOT more floor noise. The Sony is crystal clear. I was also a bit discouraged by some bad reviews of the Tascam, but I can't put my hand on these links right now, I'll post these if I find them back.
The PCM-M10 also has a very cool 5 sec pre-rec buffer function. That means, with this activated, the recording starts actually 5 sec *before* the moment you press the button. Cool for recording intermittent noises.
I also used the links you posted, but they haven't been updated for a while.
For my researches, I found the taperssection forums have a lot of useful info about everything related to field recording : http://www.taperssection.com/
hope that helps a bit
