I have built the FOD-Track, and can vouch for its ease of construction and 
it's functionality.  I am currently building the SatTracker688 (recently 
featured in the AMSAT Journal) interface by Mark Spencer of the ARRL, and it 
is also fairly easy to build (1 surface-mount IC if you build it for USB 
instead of RS-232).  The FOD-Track will cost about $20 in parts, while the 
USB version of the SatTracker688 will run closer to $40 (unless you have a 
well-stocked junk box...)

I had a quantity of FOD-Track boards made, and sold them on 
rec.radio.amateur.space several years ago.  I have 1 left, if you are 
interested.  The schematic, parts layout, and instructions are all available 
from the AMSAT software page.
