First you need to know want kind of diving you will be doing.If doing all warm water diving any balance reg will do .Just make sure it is balanced reg.My opinion go with a back inflation bc,Plate and wing ,transpack,or bcd .Not the greatest on the surface but will make it easier to swin level in the water.Mask ,what ever feels comfortable and makes a good seal on your face.Fins, I think Mares makes he best fins but I use frog fins .they work best off NJ.Exposure suit.it dependswhere you will be diving and how your body handles the temp.Buy a dive computor.It does not have to be very expensive one.Just make sure it does nitrox.Have fun and dive safe
