What rim you need has too many variables (width of tire to be used, your weight, balance of road/off-road usage and roughness of off-road use, budget, etc.) that you have not mentioned for anyone to give an appropriate recommendation.
Secondly, unless the rims are both bent it's a waste of money and effort to replace them, as good quality rims and spokes alone (a new rim may need different length spokes) could cost almost as much as the original cost of the bike ($119), let alone when you add labor.
Finally, worrying about "ultra light" rims, especially on a bike that weighs 35+ lbs, is useless. Shaving off ounces when the bike and rider together could weigh 200 lbs. is not going to make it faster or easier to pedal.
