I uploaded a schematic that does what Dana described.  I just hacked
it out by hand as that is all the time I had right at the moment.

I did not put the component values on there.  But, that is easy
enough.  They can vary some depending on the size of the pots in the
joystick you find to use.  R1 and R2 are optional if the joystick pot
is large enough.  Dana asked for zero when the joystick returned to
center.  So, I put in trim pots to adjust that.  I put in X and Y
range pots so you could adjust the output.  The range of this control
depends on the size of the other resistors selected.  The range
control can be omitted and set to any range by the feedback resistor.

There are MANY ways to design a joystick circuit.  This is just one
example that is dirt simple and cost almost nothing.  Like most
modules, most of the money is in the mechanical parts, the PCB, the
panel, the knobs.  You can make something this small on a little $2
protoboard as a one-off.

Sorry for the DIY content for those not interested.  But, the
potential for these to become dot com format available is certainly a
possibility.
