My playfield trolley arrived today. I'm not a carpenter so I outsourced the construction and design tweeking to a fellow pinball mate who did a marvelous job.
This type of unit I would not think is intended for the average person, however anyone who is regularly shopping games or doing playfield swaps this is perfect.
Considering I'm on my second playfield swap already for 2013, it will come in handy.
If you are doing any "High End Restorations", I have some second hand (but in good working order) Gottlieb rollover switches and bunnings electrical tape
