At such a low price point, I wouldn't worry too much about the bike you buy, as long as it is made by a known manufacturer. They all will have almost the same components anyway (low end shimano EZ-fire shifters + shimano tourney/2300 mech etc...).
However, carrera bikes might be 20% cheaper for the same component bike of more famous brands like Dawes, Giant, Specialized, trek..
So again, if I was you, I would go for one of the carrera bikes, like the gryphon.
