20 used deep button leafswitch button holders for 25 shipped in the states
All will need to be cleaned and or stripped of any cut wires (desoldered) but are in overall good shape
Lizard lick and other vendors sell these for 3.50 each
I have enough for 2 sets of 20
Depending on your layout this should be enough to do an entire control panel 7 buttons for each player, coin 1 and 2 Player 1 and 2 start and 2 admin buttons
Pay pal is fine
