Engel makes an awesome bait cooler, they have the 13qt, 19 and a 30qt. The aerator that comes with them are not worth two cents (my opinion), but the coolers themselves are top notch. Also, I like a good modified 5 gallon bucket with lid and insulated liner and aerator, a lot cheaper then a bait cooler, but got to be careful in rougher water or roads when in transport. The Engel shines in transport, you lock the lid on it and don't have to worry about it losing your bait.
