I'd be very surprised if any of those plastic turntables were anything
but utter crap.  But then they're aimed at the MP3/iPod users, where
audio quality is the least thing on their mind...
Considering the quality of the analog to digital converter most
people are going to be using, it probably would not be much better
using a quality turntable, cartridge, and preamp. The A to D
converter in the sound cards of most computers is not that great.
(Good enough for mp3, but that is about it.)

What sound cards (that have Linux drivers) would you recommand for
very high fidelity stereo digitising?  I have two purposes.  One is a new
interest in audio work.

Another is a project in which I need to digitise and analyse two
related analogue waveforms.  Low noise, good linearity, flat
freq. response down to 5 Hz, sampling rate of (at least)
192 Ksamples/sec are my initial specifications.  The flat response is only
a "want".  I can calibrate out any deviations if they are not severe
(like being at -60dB at 5 Hz :-).


You probably want to start here: http://ccrma.stanford.edu/planetccrma/software/ for anything resembling professional audio On Linux.
