The worst machine I own is WH20. Working underneath the mini playfield while its still attached to the main playfield is just asking for a lost screw. It doesn't help that the bulbs and flipper are a pain in the ass to change/adjust either. Whenever I shopped out my WH20, I found a nut, 2 screws and a 44 bulb in the little space in the back behind the ramps lol.
