Some people think highly of AT&T Comsphere modems also. I would not
dismiss USR Sportsters for bidirectional PPP though if you're on a
tight budget - I've got one on a Solaris box here running dp-ppp and
it's solid (I would say rock solid but that would be inviting disaster).
However, since it's only v.32bis Sportster, I am planning on replacing
it with a v.34 Courier. Couriers are great, I've got a couple and everyone
I know who has one says they just plug them in and forget about them. There
is a thread going on in comp.dcom.modems about bugs with retraining in
USR modems though (both Sportster and Courier).
