It is actually probably silly to review a car seat because they are constantly updating the technology to make them safer, but this is the one we used with both children. Remember, never buy a used carseat.
At the time (2007), this was one of the lightest on the market. I made a lot of my decisions by weight since I have a bad back. Honestly, I have never heard any one complain about an infant car seat. Safety is the number one concern here, and luckily most people don't ever find out how safe their carseat actually is firsthand. Aside from weight and the all important pattern choice, and stroller compatibility (many strollers are compatible with Graco, but if you have a stroller already or one that you know you are getting, check its car seat compatibility before you buy a carseat), I would check consumer reports or similar to make sure you get the safest, most up-to-date version.
