I have to agree with what many said. If you are concerned about the bank account then DO NOT buy a pinball machine. We all would rather have more money but if you truly would feel a significant blow to your account, do not buy it.
These things are really expensive toys. You need to have you foundation covered well before spending money on things like this. Many of the suggested pins for 2k or less makes MUCH more sense
....and for the love of god - don't take a loan out for one.
