Do you need to have absolute reading (that is, when power is restored, do
you want
to be able to read the absolute position?).

Does it have to be resistive ?

How about using an optical encoder ?

Search DigiKey for 'encoder' (and then select Encoders from the Switches
category).

BTW, every cheap mechanical mouse has a pair of them.
