The Tascam DR-07mkII records unbelievable quality. I was pleasantly surprised. Pretty straight forward to use, but you need to briefly read the instructions. It comes with 2GB micro SD (which is ample recording space), USB cable and 2 AA batteries.
I found making room/meeting recordings I needed to reduce the headphones volume and increase the record levels (using skip bttns >>), otherwise the volume of the recordings were too low when played on your computer. Works fine with Mac OS, and you don't need a micro SD card reader.
Its true that you can't really hold the device when recording as the mics are very sensitive, and picks up sound through the casing. However the Hama Table-Top Tripod with Removable Telescopic Tube
was the perfect partner - even though its £13 it's well worth it; the rubber feet and soft grip handle made it possible to make recordings while holding it, although still best on the tripod. I was amazed that I could record the ambient noise of a room, clocks ticking, and voices as clear as listening to them live. That chap who only gave it 2 stars to record his lectures should try this tripod. The Tascam's mics are sensitive enough to record from a distance.
I've not tried it outdoors, but a windjammer is essential. For close-up voice recordings (even indoors) a foam windshield is needed to reduce blow noises (you know what I mean!).
The DR-07 is much better than my Samson USB mic, the joy is that I don't need to drag cables around, and the sensitivity will record anything in a room.
If you are toying with the idea of getting this Tascam - go for it, its a brilliant piece of kit for the money.
