Here's my favorite mini-toggle setup. It's the ol' Dan Armstrong
three-mini-toggles for twelve tones scheme. I had one of my Strats wired like this, and it's not as confusing as it seems at first glance - it actually makes pretty good sense after you've played it for a bit. All the "magnificent seven" parallel combos are there, and the rest are fat series and series/parallel combos.
Note that the bridge toggle is an on/ON/on three-way, the mid and neck toggles are on/on (two-way). You can get these at Stewart-MacDonald, RadioShack, and many other fine establishments.
