Best low profile ATO unit?

[mavjoy]

I'm looking at other options for my ATO, 'cause my autotopoff brand is taking too much space inside my already packed sump. I know the tunze osmo is nice and reliable but price is pretty high. Anyone tried the Avast Marine Works auto top off? Really like how small the footprint is. Any other suggestions are appreciated. Thanks!

I really like the new Elos ATO. I am not sure how it stacks up to others price wise.

The Elos ATO should be a good fit and very similar to the tunze osmo. Price wise is almost the same but both are very reliable.
