Water pump for a drainage tub

[Fishdude]

So I think I've mentioned something like this before, but now I'm interested in recommendations for an auto sump/pump that I can use to push water into my utility sink after it drains from my overflow lines. Essentially I'll have a 100g basin pumping fresh water into the tanks and overflowing into a 40/50 gallon tub beside the sink. I want a pump that will switch on automatically when I do these water changes so I can focus on the water going into the tanks without worrying about the basin overflowing onto my floor.
