Best ATO for a 28g Nano Cube

[NickNiz]

I should finally be able to set up my Nano Cube this weekend, and I'm considering an ATO since I don't use a hood. I've done some research, but wanted more opinions...

I'm looking for an ATO with a sensor small enough to fit behind the stock media rack in the middle chamber since I think? that's going to be the one with decreasing water level. Since the back of the tank is clear, I should be fine with a laser sensor too.. Right? Also looking for something safe, maybe with an overflow prevention feature, but that's not absolutely necessary.

Does anyone have recommendations? I'm looking into the Tunze Nano ATO right now but don't want to go much higher than that in price (~$100). Just to clarify, this comes with a pump and everything else needed right? This is going to be my first ATO so I'm clueless on this stuff. Thank you!

The Tunze 3152 Nano is an aio self sufficient ATO. I'm on my second pump in 3 1/2 years but that may have been my fault by running a Kalkwasser mix through it to boost up my pH. It's fairly small, it uses the standard size Tunze magnets which I believe are 2 inch diameter by 1/2 thick. Then the cover and float switch is I think about 1 inch by 1 inch. You may want to place a 1/4 inch piece of plexi between the magnets as they are VERY strong.
