Another vote for plastic containers.
Found some nice small, but tall containers at Wal-Mart (Sterlite was mfg @ $3.50 ea), that have handles on top and they stack. They hold almost every bottle I have standing upright and are see through, so I can see what's in them.
Also keep everything in the house, as most things say they should be stored between 55-75 deg (or something close to that).
Still looking for the best storage for my 'growing' MF collection ;-)
