I agree, serial cable is a must. Here's one a bit cheaper and on

Greg, buying a serial debug cable really is necessary if you intend
to do anything serious with the BBB. However . . .

According to the PL2303HX datasheet it is 3v3 TTL, but double check
for yourself. I've seen these cheap USB<->Serial converters go for as
low as 2-3 USD. Cables, 6 bux US is about as low as I remember having
seen them. From what I understand they're also supposed to be fairly
decent, but as with anything else YMMV.

Not on prime, but only 2.43.

I've got several similar to this based on a Maxim 3232 chip. Supports
both 3.3 and 5 volts.

The shipping on the above rather kills the low price. I ordered mine
from China and the slow boat shipping, typically 3 to 4 weeks. They are
very versatile little boards.
Another option if you have a level converter handy is use your Rpi to
get the serial output from the BBB. If memory serves the Rpi is 5 volt
on everything.
