My "minner buckets" :
1 Handi-way Bait Bucket by Noble Designs - vinyl collapsible bait bucket w/clear plastic, zipper closed top, & attached air pump (don't think it's mfg'd any longer)
2 Frabill Flow-troll minnow buckets (6qt)
2 four qt individual bait buckets (brand name unknown) for use inside the boat, while the main bucket is in the water (tied to boat cleat)
1 Woodstream metal 2pc galvanized minnow bucket
Mr Little .... don't know about the bucket you saw, but Cabela's has this one : Longer-Life Insulated Soft-Sided Bait Bucket, Aerators, Bait Keepers, & Fish Lights, Fish Attractant & Bait, Fishing : Cabelas.com
Not sure about the Champagne style buckets (w/wire cage frame) ... can't remember the last time I saw one on the shelf. :o
I keep my buckets from blowing out of the boat, by putting them in my vehicle ... boat storage box ... or, if no room anywhere else, under the boat's driver console (& tied to the steering wheel). That is, of course, if they're empty. If they're still holding minnows ... they'd ride in the livewell. :D
If/when I do puchase minnows, whether for a "less than 1hr drive" to the lake or a extended stay trip .... I buy my minnows from a local store that bags them w/oxygen blown in. I've done that with as few as 4doz, and as many as a couple of pounds of minnows .... for a 1hr trip, to as long as a 4hr trip to the lake .... in the livewell of the boat (in most cases), so that in the event of a rupture of the bag, the minnows would still be contained & have water (but, no ruptures have occurred, so far). Hands Clapping
Plano, Frabill, & Challenge (brands) all make many different sizes & styles of minnow buckets ... plus there's also a styrofoam insert for a 5gal bucket, and lids, that could be purchased for a DIY minnow bucket. Some have even used coolers, and rigged a air pump to them.
What you need would depend on how you intend to use the bucket, how much room you have for it, what conditions it will be used in, and how big it has to be ... plus, whether it has to remain in the boat, or not.
