I have one. They're not that hard to find. They have them at Target and Babies R Us. I got mine with a stroller for $180 (I think). The seat is heavier than a normal infant seat, though. It weighs like 12lbs on it's own. My almost 6mo is like 16lbs right now and I can barely lift him in it. I leave that to hubby (we have a pick-up so you have to lift him up into it, the seats are above my waist, then climb in and get the thing in the middle seat).
I like the seat, though. It goes from 5lbs-35lbs and up to 32" in length, I think. My baby will outgrow the length before the weight, though. He's already 27.5" but won't outgrow it as quickly as the seats we had for our older kids. We wanted it to last as long as possible. My older son outgrew his seat at 4 months because he hit the 26" limit and was almost 20lbs.
