I'm using an MP10 and a Nero 3 right now. There are some benefits to the ecotech pumps but they come with some serious draw backs. I love the pump but the wet side has to be replaced a lot. In two years I've already gone through two wetsides and I'm on my third. They're about sixty bucks a piece for an MP10 wet side so that's where I start to wonder if they're worth the money when a cheaper pump will last longer. The ceramic shaft in the center just doesn't hold up very long. Aside from that, the programability you get from them and the fact that it keeps the wire out of the tank is awesome. I like that you can replace the parts when they go bad though instead of having to buy a whole new pump.
If it were me, I'd go with the Nero 5. The ceramic shaft in those are beefy and they push a TON of water. the My AI app is practically identical to Mobious (same company) and even though they don't have all the settings that you'd get from an MP40, I think it's a better bang for the buck. It'll last longer for the money spent.
