What is your budget. FWIW the tunze is so expensive because it comes with a pump. However, the pump is not suitable for kalkwasser. This reason steered me away from the Tunze. I have used float switches in the past with great success and currently use a jbj ato and have no complaints about it. You do also have to buy an additional pump so take that into consideration as well.
