Shearwater Peregrine. I own a Peregrine (and a Perdix AI). Fantastic computers and they don't pull that "protecting you from yourself" garbage.
I like the Peregrine and it is a very respectable dive computer that keep up with your skills right through Adv Nitrox/Deco procedures. I did wish it came with AI, the compass I could live without. Still a great computer though.
