And that's the catch (price). The reason I build my own sensors is due
to
the price. A touch sensor is a miniture momentary-on push-button
mounted
inside a block (with a wire and alligator clips to connect to the RCX).
Basically free except for my time.
I just finished building a real nice light sensor. I pulled the sensor
from
a dead alarm clock (had the sensor to dim the display at night) and
mounted
it in a Mega-Block (I just can't bring myself to cut up a Lego block).
Again
wires and clips. Another 'free' sensor for my collection.
There's lots of ideas out there, but by the time you put them into
production
and add the various levels of profit, I can't see them being more than a
few
dollars different that what's out there now.

This is where the potential is. I spent a LOT of time building a
solenoid-based
controller. It works, but I'm not really satisfied with it. Some well
designed alternate output devices (at a REASONABLE price) would be
great.
