Hi Dave - I saw one that is plastic, acts like a cradle type(no axle) that the spools just drop into. I'm in Chi. Suburbs- I've seen them at 2-3 supply houses- Nova Tools
Speed Pull. The company is in Midlothian, IL. The unit looks big enough for 4 spools of 12 or 3 spools of 10, and it's lightweight, but it's still about 30" long.
