Yup...did the same. Why did I pay $89?

mine might be low-tech gravity fed, but it does the job. I drilled an old 20g acrylic wet/dry I had lying around (a rubbermaid container would also do the trick), added a bulkhead-1/4" quick fitting and use it for my ATO reserve. I installed it a foot or so above my sump and ran a 1/4 line to a kent float valve in my sump....whole setup cost me less than $30. I recently added a 2nd bulkhead at the top of my ATO reserve tank to overflow into my 30g rubbermaid saltwater mix container.

If I get the JBJ Auto don't I need other supplies than just that monitor.. or do they come with it?
