I've got enough Phoenix Reborns, CE3's, carto's and stardusts to last about 8 months. I'm set for batteries for about a year, and have a 4 month supply of juice on hand (some of it are juices I hate though ).
I plan on adding more juice, a mechanical mod, and a couple of rebuildables to my collection. I figure that within a few months of "doomday" if it ever happens, there will be some workarounds available. The consumer market is just too strong for a complete shutdown.
