Seconded. Even to the part about formerly using Sabol but now buying Games Plus.
Alternately, magnetizing your miniatures will work; just get a cookie sheet from the dollar store and glue it to the bottom of your storage container. Also, you don't need fancy magnets. There are business card sized self-adhesive magnets sold at Office Depot to make instant refrigerator magnets. I used these for Clan War, the (short-lived) L5R miniatures game.
As for tackle boxes, they are not that cheap, and they usually don't work well as there is wasted space in the smaller trays which were meant for lures, hooks etc, but won't fit 25mm or larger minis.

I used to use Sabol, but now I buy Games Plus trays from Miniaturemarket. Cheap and they work well (and are the same dimensions as Sabol trays).
