I have the one shown above, sticking on the side of my toolbox. The base magnets seem to work fine but I would like the bit magnet to be a little stronger. Haven't lost any bits, but I wouldn't trust it with long bits.
Or if you just want a "tray" for drawers never rule out the swing area at TSC the second you walk in the doors. I buy stuff like this on clearance all the time -- for sacrificial bits if nothing else
