Thinking about getting an insulated bait tank to keep the shad alive in. Grayline seems to be the top of the line, but they're apparently made from gold based on the price. Was just reading about the KeepAlive brand tanks and they're a lot more reasonable on price, but I can't tell what the difference is between the two brands. I talked to the guy at Grayline and they're coming out with a new 25 gallon model that isn't shown on the web site yet - it's round, 22" diameter by 24" tall and has a built-in filter box. List price is $375 as compared to $420 for the current model 20 gallon tank. I'd consider building something on my own if I though I had a chance of doing a good job and saving some money. Any opinions about either brands or going the home-built route?
