the Aqualung Titan LX Supreme...
its a great reg with coldwater capabilities and a long history of quality AND its a great bargain... right around $300. You could Easily spend twice as much on a reg and not be able to discern ANY difference in workability.
Also , maybe for your first year of diving you could forgo the computer and get Solid on your tables... this will also allow you to put more money towards the things that Really count (reg and BC).
I find that for my local diving, quarries.... less than 80'... rarely exceeding two dives/day that I dont Need a computer. Sure they're convenient and flashy, but unless your doing 5 dives/day and Really need to squeeze the most out of your bottom times/surface interval efficiency I think you'd be better off putting that computer money towards more important gear. Its the decision I made for myself when I got certed this year, and I still may not buy a computer next year either... we'll see... , its just not Needed for the type of diving I do and I find myself comfortable with the tables.
