Welcome! Beware of pinball math! Pinball math is the self justification of the numbers associated with thinking about: the size of the space for the next piece, the cost of gas money to go get it, the price, the number of days extra to work to afford it, the time spent playing it compared to all other time spent doing anything else, the presumed inflation value when you sell it in order to afford the next two, the size of the space for the next two, the cost of getting them shipped, the days off needed to properly set them up, the time and cost of the repairs of the machines you already have plus the ones you just got, the travel distance to the nearest site or event to check out other machines you might be interested in but can’t afford, the amount of time and energy it will take to afford them, the detailed measurements of the small amount of remaining space left to put them, the credit card fees to purchase at least one of them as you are now dealing with your first NIB, the cost of the add on to the house in order to fit more, the time you wish your wife would play more so she could understand your delusional math justifications, and so on… (all this and I didn’t even mention the OCD numbers associated with actually playing them - the rules, scores, etc)… Have fun!!!
