I’m also a new diver. I went through divers-supply.com and leisurepro.com; was able to fully outfit for about $1600. I didn’t buy top of the line gear but what I have is adequate to get me started and help me gain valuable diving experience. Here’s what I purchased:
Henderson Thermoprene 8/7mm semi dry suit with integrated hood - $300
Mares Puck Pro computer - $160
Sea Elite BCD with integrated weight pouches + Sea Elite primary, reg, octo and gauge console with depth pressure and compass - $650
Henderson 5mm gloves - $24
2x 80 Alum. Tanks - $320
Knife and other accesories - approx. $200
As stated: not all top of the line gear but good enough to get me going so I can start building my dive log.
