I was going to recommend S'N'S too.

For what its worth I have had multiple dealings with Britax and in my experience their after sales customer service is outstanding. They fixed an issue with one of my child seats and in QA'ing it they also found and fixed two other issues that I wouldnt have know about. Now this seat I bought for DS1, so its 5 years old and Id expect straps to wear etc - there were no major faults witht he seat just wear and tear, but this was still covered by warranty.

Both my babies were over 10lb and fitten in there with the insert with no probs at all.
