New Car Seat?

Sooo. Let's be real... I'm not going to be able to get the Foonf.
So, I started looking into new car seats again.
I'm thinking of getting Kayelynn the Diono Radian RXT.
I want to get either Spring or Plum.
It rear faces to 45.
Forward faces to 80 in a 5 point harness.
Boosters up to 120.
I'm thinking that IF we get that, Kayelynn's car seat will go to Paige. Right now Paige is in a high back booster. She meets the weight and height requirements - But I'm not comfortable with it.
Kayelynn's car seat is less than a year old and Paige will be able to use it until she reaches 100 pounds.
I LOVE Kayelynn's car seat.. But after FF Kayelynn a couple of times I think the seat def. FF better than it RF's. It was so easy to get it to FF. Even in my huge car it doesn't recline at the right level - even with a rolled up towel like it says in the manual.

I LOVE this print!!
