Tomato advice please

I grow money maker too. The seed is cheap or even given away on magazines and they make excellent chutney. It may be my very hot greenhouse that they like but when I ask anyone to choose their favourite from the 3 varieties I usually grow, Money Maker, Shirley and Sun Gold, the Money Maker is chosen more often than the others. One of the reason I continue with Shirley - other than the toms are so beautiful to look at - is the plants go on much longer than  Money Maker. I can keep Shirley going right into January when I get fed up with looking after them and pull them up.
