I'm also not sure which sensor kit (or individual parts) I may

instructions and that's it. I'm happy to buy the parts needed to
install the thing, I just need to know which parts to buy?

Fred, the sensor is just a reed switch, the normally open type. You
can find it at any electronics supply store (radio shack kind of
store). It is very cheap and with a soldering iron and some patience
you can build your own sensor. I've done lots of sensors when I had a
PaceMaker3, they does not have support here, so I could not buy an
"official" sensor so I had to build mine and home made reed switch
sensor worked flawless, I even won a few races with this setup... :-)
The reed switch is a little glass thingy, very fragile, that closes
(or opens, you want the one that closes) when a magnet is near.

As HWD pointed out, the positioning is critical, because if the magnet
is too close to the reed switch the computer will register twice for
each wheel turn. If too far, the computer sometimes "miss" the wheel
turn. Either way is not good and you should test, test, test, test...

I crafted a little epoxy gnome with the reed switch inside, was fun
having a gnome riding on my fork. Chicks digs gnomes, you know... ;-)

As for the magnet, any mountain or street pedal bike shop carry those,
as they are the same as of the bicicle computers. If they aren't the
same, I don't really know, all I know is that bicicle computer magnets
work great. I zip tied mine with the help a few drops of Araldite glue
on the wheel, where the spokes cross each other and never had a
problem.
