Either go for the gold and get the britax frontier or get the evenflo maestro. The nautilus just isn't worth the extra money over the maestro IMO. Remember that there are no guarantees that any of these seats will work as a booster when the time comes, so you may (or may not) have to buy a dedicated booster when he's ready for the seatbelt. The frontier has the greatest chance of working as a booster, but if it's not in your budget, I certainly wouldn't stress myself over it. The frontier is around $300, the nautilus is $150+, and the maestro is $80. You could get the maestro and then a really nice booster for less than the frontier or about the same as the nautilus. The nautilus has the least chance of working well as a booster.
I just got my Britax Frontier last week & really like it.
Got it at Pishposhbaby.com
I used coupon code frontier25 & got 25% off & free shipping
There is also code britax20 for 20% off
Price on website is $279.99 & I ended up paying $210
Problem is they only have the cow print & Maui blue (even if it lets you purchase in another color they will e-mail you) I did the Maui blue & really like it.
