I would like to know if anyone has used a Mares Proton V32 XL regulator set. It is one of their new ones. I am looking for a first time reg for my wife and I and happended to find a great deal on that particular reg through an authorized dealer. It normally runs $589, but is on sale for $299. I had been looking at the Aqualung Titan LXand the Scubapro S550 Mk16 as other possible regs. Any thoughts on these would be great, especially the Mares. Thanks for any help you may provide.
