Convertible car seat

ALF
Anyone's LO already growing out of their infant car seat?  My LO will turn six months this week and is starting to bust out of his infant seat so time to start shopping for a convertible car seat.  I'm bummed because I'm really going to miss being able to click him in and out of the stroller and car seat base.  
Anyone have recommendations for a convertible car seat they like? TIA!
