Undoubtably the profit margin isn't much on the bait tanks. I had read good reports on the G& M tanks,speedy service,in stock and good quality,the price was in there with the superbait tanks2. Price is what I heard made the Creekbank tank owner stop producing tanks,they are very nice too, I have a friend that had one. Like I said earlier any brand of a insulated,filtered tank will be a good tank. I'm thinking if you're just wanting a holding tank for home you could Probally make one that would work fine for that. Robert Wood,,bobsbait on here had a chiller a while back. I have a 240 gal.round tank that I bought from Bob over 10 years ago that works well in the cooler months for shad,it's got a pond pump in it that pumps up into a filter bucket and a couple of aireation pumps. I've hauled many many dozen herring in it for long range trips .i could send you a picture of it if you'd like,. Sam
