For ~100 dB dynamic range, you probably want the Delta 44 sound card.
Flex now recommends the Edirol 66 but the Delta 44 is less expensive
and will be OK for ~100 dB dynamic range.

May 2007 QST had a nice review of sound cards here:

For a less expensive alternatives, older cards that
Flex once supported were SoundBlaster Audigy2
ZS, Audigy2, Extigy, MP3+ and the Turtle Beach Santa
Cruz.  Probably several of these are available used
for low cost on eBay.  But remember that your sound
card is the determining factor for dynamic range and
display bandwidth.
