The venerable KPC-3 from Kantronics is always a good choice as well.

Apologies if this is very naive and thoroughly uninformed (it is) and
possibly stupid, but seeing this on the above page --
Data Rate (radio port) 1200 bps (default); 300, 400, 600
-- do these TNCs offer the same data transmission speeds that people
used to get with early generation modems and acoustic couplers way
back when? So what are people using TNCs for, then? What data are you
actually exchanging this way? What are the modern-day practical
applications of this technology? You're probably not using this to
download install44.iso...
Yes. The normal speed for packet radio over UHF/SHV is 1200 or 9600
bps, over HF usually 300 bps.
Heck, a very popular tranmission technique on HF, PSK31, uses 31 bps.
Maybe you should google a bit a see what TNCs are used for ;)
