Bucket aerator recommendation?

[Shakespeare]

I did a forum search on "aerator" but didn't cough up what I was looking for. I'm thinking about taking one of those insulated orange water coolers and making a portable live bait bucket out of it. I've been looking at the Marine Metal Bubbles aerator... the one that takes a couple of D cell batteries and using it for my aeration. Just wanted to see if anyone has a better product recommendation or some helpful hints for putting this together. Thanks!
