You should definately wait a while before making any purchase besides mask, fins, & snorkel. Like many divers, I wanted my own equipment and bought quickly on the recommendation of friends and the dive shop I got certified at. Within a year I had different fins, a different dive computer, and a different tank. Within two years the reg and BC were upgraded as well...with the wasted $$ eating up any differential in price between the LDS and on-lien prices!
Once you know what you want, then definately do the research on-line to get a sense of a "fair" price. Keep in mind that no on-line shop can help you with getting a proper fit, assembling gear once you get it, dealing with warranty issues for you, etc. At most I'd only buy on-line things that are relatively low tech without much complexity or 'fit' issues ... fins, tanks, etc.
There are very real risks, however, to getting the lowest price on-line that you need to be aware of. I bought an expensive dive light and battery pack from LeisurePro, for example. The light leaked on the first dive, the batteries leaked acid and ruined the very expensive light. The manufacturer's didn't warranty anything bought from LeisurePro....in the end they were kind enough to sell me another at their cost, but I had to 'eat crow' at my LDS first. I've seen people buy "standard" BC's , tanks, and regs on-line for great prices ... but then find out that they were from another country, with different specifications on connections, etc. Some of the stuff sold as "new" on-line is actually defective equipment that is repaired and re-sold ... I saw a guy with a 'new' BC the same brand as mine that leaked terribly on the first dive. Because he bought it on-line the manufacturer refused to warranty it, and he was out of luck.
At the end of the day the issue is whether you want to support your local dive shop. My answer is yes ... no on-line shop gives me free air, gives me real-time tips to improve my diving, helps me configure my gear, and I want the LDS to be rewarded for that. Do they charge a premium? Certainly....my sense is that a 20% to 30% premium is 'fair.' If a legitimate dive shop has a lower price, tell them about it and ask if they'll meet it (often they will). Many will order in equipment for you that they don't normally carry.
