I, too, would strongly recommend a Keyspan adapter. They had one of
the first Mac units on the market, and have always had great drivers.
They are a very Mac friendly company.

I've compiled old UNIX code under OS X (some modem/TTY stuff), and
had no problems getting it to work with the adapters. The device
name is a bit strange and it changes if you change USB ports (even
on a hub), but besides that, they're easy to work with. You can even
have multiple adapters hooked up to the same machine.
I even went so far as to configure a getty on one of the serial
ports. I was able to hookup an old VT-220 (yes, the real thing) and
login to my Powerbook. I was actually a bit surprised it worked, but it
did exactly what it should have done. Pretty cool for us old-school
UNIX types, although using a big terminal to login to a tiny
Powerbook sitting on top was amusing, to say the least.
