Have to change power input from 120V/60Hz to 230V/50Hz

Hi,
I am using the CVA-2660 in the US with 120V/60Hz power supply. Now I am preparing for the move to Singapore where they have 230V/50Hz power supply. What should I do? Get a transformer 230V>>120V would be one option I guess. But is there a better solution like getting the suitable 230V/50Hz power supply and install it inside the machine? Or are there motors inside the machine that are running on 120V?? In this case I assume it would be too expensive and troublesome to replace those with the 230V version I need in Singapore. 
Greetings,
