If you are going to be spending a lot of money on scuba gear and don't have any plans to go into tech, then look to save some money on a computer. Victor gave good advice. I will only add that user-replaceable batteries are a good thing, and being able to go into gauge mode will be very nice for you in case you do unexpectedly decide to go into tech. There was a time in my life when I saw nothing in my diving future but warm tropical reefs. Now I am mostly doing the things I thought I would never do.
That's a great point regarding the user-replaceable batteries and the gauge mode. I hinted at gauge mode, but didn't come out and say it. The DG03 has a user-replaceable battery, but you have to get a spare while you have civilization around you....don't count on getting one in the middle of a big dive trip. The Petrel uses the ultra-rare "AA" battery. Wait, not rare....
As for never going in to Tech diving.....be VERY careful saying that. I swore I'd never be a tech/cave diver and I'd never own any tanks. I've got 9 tanks in my house, pricing out a few more, and I'm a lightweight amongst my peers. Plus, I'm certified Deco and Cave and looking into Trimix.
