You really can't go wrong with anything by Safe N Sound. I have a Premier retractor which has been great and I have a Royale, also very good. They all pretty much work the same, some are just fancier than others (the Meridian has lots of extra padding, AHR, etc.).

Baby Love is a good brand too (Australian made), but I personally don't like them as much as Safe N Sound car seats. But they are a bit more affordable, they are good quality and exceed the Australian standards. I also think their seats are a bit wider than the SNS ones.

I have heard mixed things about Turn-a-tots. I've sold a couple of them second-hand in the past and they seem much heavier and bulkier than the Safe-N-Sound car seats. Some people love them though.

Good luck deciding
