Have been looking at carseats, and originally I was thinking of the turn-a-tot as we have a 4WD and it seems so much easier (having two friends who rave of them), but then I can't seem to go past the SNS seats, have been looking at the Meridian AHR Retractor and tonight found the Platinum AHR Retractor, the only real difference I can find is that the Platinum has built in speakers... can anyone tell me if this is worth anything or just a gimic? When we drive, apart from running around small town, we will be driving a min of 5hrs to get anywhere so I'm willing to spend the $$ on a car seat but wasn't sure if these of any use. Seems to be only $30 difference.

Any recommendations or advice would be much appreciated Thanks in advance
