I fear soldering, and don't understand a lot of technical drawings
(regardless of how many wiring classes I've taken :D ).  So I bought
my IR Receiver, and really like it!  It's one of the serial cases
wrapped around a board, with 3 wires sticking out where the IR
receiver itself is.

Anyway, to my point:
I can't remember where I bought it (pity, I really like it).  Any
chance you are looking at mass producing like 5 of these for a small
price.  I paid somewhere in the $15 USD ballpark which included
shipping for the one I have.
Just a thought, when I build more boxes, I always end up dragging the
one I have to the one I'm currently using, quite a pain when more than
1 TV is wanting to be watched.
