Moneymakers are an indeterminate variety, wg, meaning they will keep on growing and producing fruit during the season. They can reach 6' or more unless you nip out the growing tips. For indeterminates, as a rule of thumb, the bigger the pot the better to let them reach their full potential.
Given that, you also have to factor in your available space, including access to sunlight for as long as possible during the day, and how many plants you want.
Once you get into pots below 30cm (in diameter) you start to compromise their potential. But, as I say, you are ultimately at the mercy of the available space.
One important thing, though. The plants will need to be staked and tied up to the stakes. Stakes in pots can be a problem if the pot isn't deep enough to give the stake decent stability. A strong wind can tip everything over.
