Whether or not he has just received inheritance, is a multimillionaire evil genius, or is a very successful business man who has already helped millions with his money... I say if that's what he wants to buy, why the hell not?! lol
I think if I had just won the Euromillions jackpot (this Friday estimated @ £12,000,000) I would probably never worry about money again. I would love to buy this machine, just for the sake of it. I would still have a load of money left over for helping myself and others as and how I wished.
However, if you think you may regret it in any way, you most definitely shouldn't buy it
