Affordable and light weight forward facing car seat

Hi guys, can someone recommend a cheap and light weight forward facing car seat? I need one as a back up for my daughter (almost 3 years old, but 40in tall and 39lbs). I have the Graco4ever as her main car seat, but need something as a backup for when I forget the carseat in my husbands car etc. And yes, I’m aware of the benefits of rear facing longer, she’s still rear facing in her current main car seat, I’m asking for forward facing because of her weight and height, I’m not interested in buying another car seat to only last for a few month. TIA!
