BCD - SeaQuest Pro QD+ with Air Source Complete
Seaquest makes a good, reliable BC. If jacket style is what you want, you'll likely be very happy with the Pro QD+ . Personally, I'd never buy an integrated air source if a reliable octo could be purchased instead. IMHO, it's extra money for less functionality and security in an emergency, but others disagree. Personally, I wouldn't want to have to breathe out of the same hose I'm using to control bouyancy while ascending with a possibly panicy or unconsious diver during an air-share for a negligable increase in streamlining, and I definately wouldn't pay extra for it, but do whatever makes you happy. If it were me, I'd get an extra second stage instead.

Regulator - Aqualung Legend LX Supreme
I don't have any experience with the Aqualung Legend LX Supreme, and have only used an Aqualand on several occasions as a rental. It was adequate, but I wasn't doing anything I'd consider particularly demanding. It has a good reputation from what I've heard though, and is supposedly easy to get parts for if it needs repairs anywhere in the world.

Computer - Uwatec Aladin Smart Computer Air/Nitrox w/ compass
I dove on a liveaboard with someone using one of these once, and I got really tired of listening to it beep at him. Way too noisy for my taste, but probably a good computer if you either don't do anything to put it in a bad mood or don't mind not having any peace and quiet when you dive.

Well... I don't know what you have, but a mask, fins, wetsuit, tanks, dive light, gear bag, reel, lift bag/smb, scooter, flag, bottom timer, jon line, wet notes, strobe light, slate, signal mirror, whistle, catch bag, speargun, and 18' RIB are all popular options.

Also, would you recommend shopping online or sticking with the local shops? As of right now, the stuff online is over $500 cheaper...
Depends on whether it's more important to you to keep the local guy in business, get warranty service, and establish a good relationship with them, or save a fat wad of cash. That's your call.
