I use a Poseidon 720P (front) and an SJ1000 (rear). The SJ1000 is the most recent and cheapest. It is compared favourably with the Hero and there's a few hundred UKP difference. The SJ1000 will do 1080P , but I have it set to 720P to conserve storage. The Poseidon suffers from a bit of tunnelling. Battery life is the only real concern but as they're easy to find and carry its not a problem (2 batts a day).
