I was in Walmart on SUnday buying diapers when a car seat started talking to me as I passed it. I am not kidding-the display actually seemed to be activated by my walking by and it started to tell me about this new all in one seat. It looked pretty cool. I forget the name, but it started with an "I". It can be used RF and FF with the harness to 40 lbs, then converts to a BPB. The cool thing is that it looked like it may really last a child a long time since the back extends like on a Turbo Booster and other similar boosters. I have no idea what the price of the seat is, as my walmart never seems to have prices posted correclty anyway!
