I need help! DD still has some time in her infant car seat but I wanted to grab a convertible I find one sale. Two days ago I found the Britax Advocate 70-G3 on NoBetterDeal for $213 (!!!!!) so I jumped on it right away. I had also had my eye in the Diono Radian RXT because of its rave reviews and that it will the only car seat I need for DD since it coverts to a booster too. Can anyone give any advice on Britax vs Diono?
