My soon to be one year old is about to inherit his big brother's RA50 Classic, and Scenera. The Scenera is in DH's car and isn't used as often. So I need two new seats for my already FF'ing 3 and a half year old. I have already decided on the new Britax Frontier 90 as the primary seat for my car, and was going to go with the Evenflo Maestro for my DH's car, as they don't ride in there a whole lot, and I didn't want anything expensive at all. Then I saw an awesome deal on a Nautilus for $95. I can get the Maestro at BRU with a 20% off coupon for about $64. Is the Nauti worth the extra $? Will it last longer than the Maestro, as I have heard this seat is outgrown before true booster age?
