How long recordings are we talking about? Resolution? Number of
channels?
It seems to me that that standard solution - a portable (walkman
size) DAT - would be a good alternative. 32..48 kHz, 16 bits, stereo,
60 or 80 minutes/casette, rotating head + buffering, so there is no
tape induced sample rate fluctuations or anything like that. Any
serious DAT has an S/PDIF interface, of course.
The most obvious disadvantages are that you're using tape (looooong
seek times), and that you can't transfer the recordings to the
computer with higher speed than "real time". (There may be computer
DATs that can read audio DAT casettes at higher speeds, though; don't
know.)
Another solution would be a laptop with plenty of HD space, an S/PDIF
interface (USB?) and a good stand-alone ADC box. (The ADC box should
preferable be one with an external power supply, or one meant to be
driven by the phantom power from a mixer mic input. Less soldering
that way.) Make sure to get a laptop with a decent 100+ Mbps NIC, if
you still need to transfer the data to another machine.
