It's not really a "net", but I picked up something like you = described at my FLAPS (Pep Boys) a while back. It's basically a bunch of bungee = cords hooked together and attached in some sort of self-centering = arrangement. I'm not sure about this since I've only used it once, but I believe it = has around 9 - 12 attachment points. It did a good job of holding in = the roof compartment a full load of several pieces of oddly-shaped driftwood that = I picked up off of an intercoastal island in North Carolina one = weekend. I don't remember the exact price, but I think it was somewhere in the $10 = - $15 range.
