Don't be in a big hurry to buy all of your gear. Get yourself a good 3/2 wetsuit, mask that fits and works for your face, folding snorkel and some good fitting fins. Before you buy from your local dive shop (LDS), go visit some others (you may be surprised at how many there are in your area) and try different brands. The shop I learned from sold a few people in my class the complete rigs. One of the couples (matching gear and all) decided that diving was not for them after their first ocean dive. Fortunately, they were able to sell their stuff to their friends (who love diving), but they could have been out lots of $.
Also, rent gear from your local dive shops and see what you like (brands, types of BCs, etc.). Not all rental gear is well maintained, but if you LDS encourages you to buy because rental gear can be ill cared for, remind them that they rent gear too and see if that happens to be their policy.
Once you decide to buy, if you by from your local shop or online (at least look to compare and make an informed decision), build your equipment set slowly with quality rather than try to get entry-level everything all at once.
