Best Temperature Controller Option? ATO?

[Beausoleiljacob]

Hi Everyone!
I need a different temperature controller. I originally bought the JBJ True Temp, but it hasn't been very reliable. I have had to reset it like 10 times in the last day. The thing never seems to turn the heater on, even if the tank is 2 degrees below the set temperature. What would you recommend? I really would LOVE an Apex, I just can't afford it. Would the Cheapest Reef keeper be an okay option? (ReefKeeper Lite).

In addition, I also bought the JBJ ATO. My return pump chamber is constantly changing. As of now that is where the float sits. Would my return pump still stay submerged if I place the ATO in the refugium? I have the Eshoppes R-100 Sump if that helps any.

I use a finnex temperature controller, have had it a couple months, so far so good.
For the ATO, do you want to run the water line into the fuge or the sensor?
The sensor needs to be where the water level drops, but I haven't had an issue with having the topoff water added to another chamber. I use the Avast marine ATO and have been very happy with it. No moving part, no maintenance, no problems.
