tunze to turn on and off

[jacob.morgan78]

What's the most affordable (cheapest) Tunze that I can purchase that doesn't mind being turned on and off repeatedly. I want to do this using an Apex controller. I like the 6025 but have read that it chatters when turning on. I don't need a lot of flow.

Thanks!
