Any size tuppaware,lock-n-lock...or similar plastic air tight container.
Thick ass freezer bags.
Any airtight container,pasta holder or bread box.
Hell,if you need to,put cigars in one ziplock,inside another ziplock with a piece of paper towel with water and hide it away from light.
For poormans storage and simplicity its hard to beat a rubbermaid container and some beads.
You could have a set up to handle 20-30 for under $30 pretty easily.
Viper for a tube of beads and a yard sale or your closest grocery store for the container.
It aint pretty enough to sit out on a desk top or anything bet then beauty is in the eye of the beholder.
You could get some wood grained contact paper for the outside if you want to go high tech redneck.

Ziplock and a humi pack will last for quite some time as long as you don't leave it in your car for a week in the summer.
One thing that I would like to add is that if you do make a coolidoor or use plastic bags, tupperwear, ect.. You should open them up every couple of days to let new airflow in. For instance if you make the coolidor leave the spicket at the bottom open, its not enough to lower the RH much but you don't have to mess with it then. If you go the smaller route open your cigars at least once a week, JMO.
