automatic top off

Claris or Elliot?
i made a top-off for my 125g using an ultralife float switch($60). i'm going to have a similar setup on my nano but don't want to spend that much again. anyone have any better/cheaper ideas?

the setup was easy:
a float switch controls an air pump that pressurizes a 5gal watercooler jug, and the pressure pushes water out of the jug into the sump. i just want a cheaper switch (floatswitches.net doesnt have any mounting solutions)
