First let me say "Don't buy yet!"
1 - Regulator. It's yours, you know the maintenence done, care, cleaning. Buy this from your LDS to ensure there are no warranty hassles. You will most likely get it serviced/repaired at the LDS and they will be appreciative that you bought it from them. Just make sure your getting a good deal.
2 - BC or BP/wing. Same main issues as regulator. In my estimation, not as critical to buy from LDS, but nice to support them.
3 - Wetsuit. Buy from the LDS where you can try on, get fit it you need to order. However, if they can't cut you a good deal, buy online.
4 - Camera & housing.
5- Dive Computer. By the time you get around to this, you should have plenty of practice with tables and have a good idea in your mind of where you should be, when you should be there. You will have choices of air integrated (take the place of your SPG for air pressure), non-integrated, air only, air/nitrox, air/nitrox/trimix. It can be confusing. But you will also have an idea of what types of diving you will be doing and/or moving into. It would be a pity and expensive to buy a computer now that was air only and then in six months decide you want your Nitrox cert.
6 - Tank(s). These you can rent easily. But after time, you may want your own for peace of mind, ability to dive when the LDS is closed, spur of the moment. If you buy new from the LDS, chances are your can get a years free air fills.
Remeber, your LDS is where you will probably be spending more time and money on training and training is not how they keep the lights on and the compressor running. Those compressors, filters, rent/mortgage, electricity, insurance, employees, etc. all cost money. It's nice to have a place to get air fills.
Above all, take your time and enjoy. Don't rush into buying stuff just yet. Rent for a bit, get comfortable with what kind of diving you want to do and what gear you want to buy.
There's a lot of good information in this post, but I do disagree with some of it.....personally, I recommend someone who plans on continuing to dive to get their exposure suit first....if you use a wetsuit, why do you want to dive in something someone else has already peed in....sorry, not me.
Second, I buy my regs......familiarity breeds confidence, and having your own reg, something you have had serviced, and/ or put your own "Sea-Cure" mouthpiece on just feels comfortable, and makes you feel better in the water.
Third, I get the BCD....again, it's life safety, and knowing it's condition and how it's treated just adds to the comfort level in the water. While you're diving in your own wetsuit and/or reg, try a few different BCDs. I currently own 3, and am buying either a transpac or a BP, and wish I had done that a couple thousand dollars ago. Try a few and find what you like before buying. A good LDS has a few different models in their rental dept.
Next, get the computer. Again, safety is all about familiarity, so get your own computer that you get used to. Having said that, don't forget your tables, as 'puters do die on dives, and knowing your tables could save your ASSS. I have glued a set of the dive tables to the back of my console, just as a back up to my 2 computers.
I honestly believe no one should be getting into the water with a camera, unless they have mastered the basic skills and have a few dozen dives under their belt, so that should go to the bottom of the list.
Of course, this list cost you nothing to read, and is worth just that....nothing. This is just my opinion as an experienced diver. You'll read many other opinions in this thread, and in the end, read them all, think it through, and make your own decision. Untimately, it's your choice, and your life.
Dive safe and Often,
