What about the mics themselves? I haven't found a good way to pack them. Sometimes I just use the original boxes and bubble wrap they came in, but they're getting pretty beat up and it's pretty cumbersome.

A few things I haven't seen mentioned yet.

All of my mic cables are carried in a 5-gallon plastic bucket. They are just the right size to hold a coiled cable, and you can fit a bunch of them in a cheap bucket. You can also get 3 and 7 gallon buckets for different amounts of cable. Spend $5 and buy a Gamma Seal screw-on lid, as they are much easier to deal with than the snap-on type.

I use a small Gator case for my hand-held mics that also has enough room for my wireless transmitters. Other mics go in a briefcase-sized foam-lined case. Connectors and adapters and such are in a large tackle box with drawers on the bottom.

I just use the zip bags that came with the mic, they have big white gaffer tape labels on them for the mic and adaptor, and those go in the Old Navy lunchboxes I mentioned previously.
