I like the Asihi Kasei(Japan) AK9201 - 10 us conversion time (so you 
can sample a stereo signal at 44.1 khz with time to spare) - mates well 
with a Burr Brown PCM56 at the D/A end . Both chips are serial at the 
digital end , so are ideal for loading into 1M*1 DRAMS for delays , 
effects etc. Downmarket a little is the Philips TDA1534,1535,1541 chipset
(A/D,S/H,D/A) - cheader , but only good for 14 bit resolution at the 
A/D end - the D/A is found in many CD players.
Let me know what others have to say on the subject , as I'm doing digitising 
stuff as well (Audio) - cheers , md.

If you're interested in sample rates below 50 kHz, you should have a
look at the Crystal 5326.  This is the converter used in the newer Sony
DAT machines.  The best thing about it is that the anti-aliasing filter
is a single R and C (it's a "one-bit" converter).  Also, you can change
the sampling rate by changing the clock rate.  The built-in
anti-aliasing filter tracks the clock rate.  It is also a stereo part.
