Default Digital audio recordings

What are folks using these days to record audio? MiniDisc, DAT or
digital audio?

Any recommendations on digital audio recorders? That's what I'd go for I
think when I begin DXing again. I've no idea what products people are using.

Zoom H2 recorder
$32 8 GByte SDHC card at Frys
$175 for H2 recorder on amazon (DJ Tools)

I believe you need to be able to record in PCM. If you record in a
compressed format, you are screwed regarding post processing. That is,
if you record in mp3, then want to enhance the recording (filtering,
etc), you need to convert to PCM, but the recording will be full of
mp3 artifacts. Then if you want to put the file on the net, the audio
quality will suffer when you compress it to mp3 again. Thus you need
large capacity and the ability to record in PCM.

The unit has a line input.

Caveats:
1) No vox. It sounds like it has one, but it doesn't. You can remove
the gaps via software, but the dead air does take up space on the SDHC
card.
2) Microphone input very noise. Not a big deal, but if you plan to
record with external microphone, you will need to use an external
microphone amp. Note the amps for the 4 internal microphones are low
noise.
3) Due to limits of fat32, files are limited to 2GBytes. If you try to
record 8Gbytes in one setting, it will break the file up into 4 2Gbyte
blocks.
4) Recording in mono does not save space on the card. It is just
stereo in two mono channels.
5) Line output is noisy. Not a big deal since it is the digital data
that is of concern.

Advantages:
1) AA powered
2) PCM
3) Line input recording is very clean.
4) Mac/PC compatible. Even works on Windows X64
5) For fun, the unit acts like a USB microphone. I've done SKYPE with
it.
6) Large user base with cool hacks like make your own surround sound
files.
