Rice cookers for Students??

Im going back to uni in september and I want to buy a rice cooker for myself to use for makeinging bentos etc. Im also trying to slim down for my graduation in the summer and im planning to try to make bentos every day im in uni to help me contol my calorie consumption (most of the food in the uni canteen is deep fried), so i think a rice cooker would be a great investment. I just have no idea which one would be the best for me, as I will mainly be cooking for just myself and Im on a butget. I would really apreciate some help and sugestions as to which rice cooker to go for.
