I'm glad the question wasn't about lottery tickets and strippers...
Well that would not be hobby expenses, but necessities. You also forgot scotch and Cuban cigars.
My original answer was 100 bucks . But after thinking about it more , I'd have to say I spend more like 2 - 3 hundred bucks a month lately . With the M1's and adding sound to other steamers , it adds up quickly !
I now have most of what I need.
Though, truth be told, like many others, I waste close too, $100 a month on useless...(not model train)...not needed stuff.
