1. What sort of price could one get for it? It is covered by a 2 year
Honeywell extended warranty, starting Oct 2004, which I believe is
transferable.

New ones are going for a bit over $1,700. I would auction it on Ebay with a
minimum bid of $850.

2. What documents, if any, would have to come with it to be useful to
an American aircraft owner? I can't issue an 8130-3 myself.

Can't help you much there except to note that an 8130-3 form is not required on
items manufactured and installed in the U.S.; it's mainly an export item. If I
read the FAQ correctly
(http://www.faa.gov/certification/aircraft/8130-3FAQ.htm)
TSO'd items also aren't subject to these forms. If I were to buy it, I would
expect copies of the original papers, including the warranty, and a statement
from the technician who removed it to the effect that it was operable at that
time.
