IBN....I've never seen or heard of it either, but I like the features that were mentioned....especially the one that operates with a button that remembers how much line is out. That could be handy. I've always been a bit leery about Zebco, when I think of that name, all I see is the old closed face standard that we all learned how to fish with. Served it's purpose, though. Isn't Quantam a Zebco subsidiary? The Quantam brand is now recognized as one of the best in the affordable line, if memory serves. Are you thinking about buying one?
