My SIL swears by the Evenflo Triumph convertible carseat. The new model goes from 5-50 lbs and she really loves it. They've been using evenflo triumphs since their first son was born in 2005 and they're really pleased. She said they have a great safety rating and they're not a million bucks. Target has a nice one for $129 online and another one for $130 in the stores. Both go up to 50 lbs. I think a convertible car seat is a good solution for people who plan to carry their babies. I see women lugging around those bucket seats and I think...the baby's sooo much lighter on his own!! Of course, I'm sure it's convenient if you don't want to wake them up.
