I am fairly new to diving and am starting to buy some of my own equipment and was wondering who has experience with these regulators? I have used the TUSA RS-680 and like it, but I have had people tell me that the Auqalung is a better brand. I am sure this has been discussed before but I could not find anything. I have not had a chance to use Aqualung but have heard good things about them. Any help or suggestions would be appreciated.
