I know all 3 can be paired with Shearwater Teric. I can get the Aqualung for $250, the Shearwater Research for $315 and the Swift for $375. I will be installing on my Aqualung Mikron 1st Stage. Obviously the cheap side of me is leaning towards the Aqualung 02 Clean haha. But is there any reason I should consider the other 2? I wont be connecting more than my own Teric.
