I personally think using an actuator and tracker circuit on the same setup is easier, but it would cost more than $35 if you're not good at scrounging.
Pros and Cons:
Actuator Circuit Pros: Programable, collects maximum power.
Cons: uses electricity, few more parts to break down.
Freon Tracker Pros: uses no electricity.
Cons: doesnt work until the panel heats up, which may take awhile since it's facing the opposite direction of the sun every day. Better hope you dont get a leak as well.
