I'll take some pics of the setup I built a few years back and post them here. Its nothing fancy, but it works really well and breaks down for easy storage.
EDIT:
Okay, here are some pics. Pretty basic setup made from scraps I had laying around the garage. The 2x4 frames screw into the plywood base, and the plywood base gets screwed into the sawhorses. The spools of twine are held on by a couple dowels and are centered 16" in from each end so that the bundles are fairly evenly tied and stable. The end caps for the spools of twine are just some hole saw drops, again, from the scrap box. I believe our town has a bundle length and diameter limit, which is why the 2x4 frame is sized as shown. The plywood base is 4' long so when loading, any limbs that stick out past the ends of the base get trimmed down or folded back into the middle. Make sure to pull out the twine before starting to load - you'll only make that mistake once or twice!

When not in use, I keep the frames assembled and use a scrap board screwed to the middles to hold them together. I just keep the pieces stashed in the rafters ready for the next storm. Setup only takes a few minutes and it saves a ton of fiddling around.

You're welcome to use this idea as long as its not for commercial purposes (I wrote that on there probably 3 years ago, haven't seen the papers from the gov't show up yet

).
