That is a nice bit of kit but a tad expensive.   Creative has a USB X-Fi that 
purports to be 24 bit but I haven't been able to find detailed specs such 
that I can sure they aren't doing goofy things like padding 16 bits out to 24 
or apply weird forms of equalization or pre-emphasis.  It is supported in 
Linux but the drivers seem dodgy and were released by Creative half-baked 
because they couldn't make it work (though improved since).  Still, it can be 
had for $60 provided I could get the skinny on it's real specs and how good 
support for it is these days.

It turns out in general inexpensive 24-bit USB audio doesn't really exist. So 
I may have to go as high as $130-$150 for a used pro device if the Creative 
device turns out to have disgusting flaws which their products often do.  

I did go a similar route to digitize my VHS collection. I got a Kingwin 
KM-31BK which can take composite in and record straight to VHS on a SATA 
hardrive which you chuck in the unit yourself..  It turned out to run an 
embedded Linux though I did have to do something about it's unfortunate 
respect for Macrovision.  I then used avidemux to edit out commercials and 
such and then crushed them down with x264.  It worked well.

Don't be irreplaceable, if you can't be replaced, you can't be promoted.
