Using 115V, 60Hz AC with 230V, 50Hz power supply

Hi, I want to buy a Frigidaire FFRA0511R1 AC from the USA to use in Europe. Due to different voltage standards, I am planning to buy a transformer, e.g. https://www.amazon.com/Rockstone-Power-Voltage-Transformer-Converter/dp/B00CLY84YW . Which characteristics should I look at? Could you list some proven transformers models under 50$?

Thank you.
