Bipe, that's a nice setup. Did you get it at one of the "big box" home improvement stores? Sorry, couldn't resist. Really, though, I like the idea of having everything nest in one spot and having removable modules if I don't need it all. Right now, I have a mess, because if I'm flying electric, I have to bring my electricians toolbag with the chargers, etc, if I'm flying the bigger glow stuff I've got to haul around the ultratote, and that just seems too big and heavy to bother with for half-a stuff. So, ideally, I need a 3-part field box. Master Cart, eh? I'll google that up now.
