For 4-5 pins, I would run two separate 20amp circuits with 12-2 wire. Better than two or one 15amp circuits with 14-2.

I know that your comment wasn't directed towards any particular person, but:
I'm not a certified electrician, but I did wire houses for 5 years before I started my current field of work. My suggestion is how I would do it if I was wiring my own home. Just a suggestion is all. I don't see the harm in asking fellow Pinsiders for help before paying some guy to tell you their opinion. Just my two cents.

BTW: Three 20amp dedicated circuits for 4-5 pinball machines is PLENTY enough. No code violations there.

Fair enough!

He quoted me $470.

Yeah, I'd say about a $375-500 job.

I did a similar job for my mom about two years ago. I added a 220V receptacle in her laundry room for an electric dryer. It took about two hours. Obviously she wasn't charged, but I would say it was about a $350 side job in my book.

In the end, I had to research code myself.

Good call.
