Re: Poker table Drop Boxes.
A friend of mine installed a budget-minded dealer toke container under his custom table.
The table surface felt has a standard token/chip/bill slot. He took a 'screw-on-top' tupperware-style container (not the 'burp' type) and made a cut-out in the lid large enough to allow any chips passed through the table-top bill slot to drop through the lid into the container. He then attached the lid to the underside of the table beneath the slot with wood screws. The container itself screws up onto the lid. You simply unscrew the container from the lid (about a quarter-turn, I'd guess) allowing the container to drop away from the table to gain access to the contents.
It's somewhat shallow (3" or so) and made of relatively soft plastic, so it doesn't interfere with the dealer's legs or movement in any way (unlike many casino drop boxes, which have taken a gash out of my knee on more than one occasion).
If security is not an issue, it works perfectly fine, and costs almost nothing.
