Lathe and tire machine opinions

I know it's definitely cheaper if not close to it to just buy new rotors or drums for the vast majority of passenger cars and trucks. And in my area they charge like $15 a piece to turn them, most less than $20 a piece to buy new. $65 for flywheels, which most you can replace new for $100. I certainly wouldn't look at it as a moneymaker, but as a sweet piece of equipment for the shop I can't go wrong. Lol. Well other than floor space, but I am going to build a loft for parts storage it could live up there.
