That's good to know!  The Arduino Mega has 4 UARTS.  But $65 seems a
little steep,  isn't the chip ~$16?   Certainly they have a nice PCB
there and it must be a pain to solder the chip on.

One could ramp up to a Make Controller / Interface board with Ethernet
for $85, and you get Ethernet and 2 serial ports ;)
