trolley is next on the list

I apologise if you have been told this 100 times already but that trolley will not fit between the legs on stardard pinball machines (if you are going in from the front).
If you want to be able to fit them between the legs you need to go one model down that is 440mm wide and not 500mm like the one you linked. Just in case you were not aware.
