I think they shouldn't be allowed to sell them really it sux they even do. Infa Secure used to have their own and stopped sale of them after the findings. Britax aren't so considerate You don't hear much about it because they are still legal to sell and use for the moment.
The new Maxis are good seats but very expensive! The Infa Secure Caprices are much cheaper with high markers, but maybe a bit more expensive than the ones you're looking at. They know how to make their money! Grrrr
