The DLP (FTDI) cables seem a little bit cheaper, and I have used them
on several 5536 platforms.

http://www.mouser.com/catalog/633/35.pdf
DLP-TTL-232R-3V3-WE is a wire-ended version ($24)
DLP-TTL-232R-3V3 is a version with a 5-pin 100mil socket already attached ($20)
DLP-TTL-232R-3V3-PCB is a blank version ($18, add your own wires)

If the thincan has 5536's first serial port RX and TX available on a
header (the Atrec person mentioned there is a daughterboard for a real
serial port), the 100mil socket version is easy, just swap the pins in
the connector as needed. The wire-ended and blank ones are generic if
it is some other connector.

The above part numbers are for the 3.3V versions, but they are 5v
tolerant, too, so you can also use them with the muxed DDC pins
(5536's 2nd serial port) if that is the intent.
