It seems reasonably priced at about $200 USD. I don't think you
could build anything cheaper than that considering development costs
and equipment.


FWIW, I have been using one of these for the last couple of years. It
has performed as advertised, and the manufacturer was responsive to my
queries.

Yes, this is a good suggestion. Actually more like the CruzPro RP-110 at
$260 which has the 4 lines I am looking for.
Following previous advices, I have sorted out the parallax combination
that would fit my needs and found that it would cost about 110$.
I have also checked that it is indeed well within my hardware/software
skills.

Thank to all of you, now I have enough information to decide.
The point now is whether I have leisure time and will to build my own
device and whether it is worth the $150 difference.

With the skyrocketing stock exchange crisis probably yes but I'll see...
:-)

Thank you again
Daniel
