I think that $120 per person for a week's worth of rentals is on the low side.Also, I think that math above was a little fuzzy. Renting equipment for a weak of vacation diving is 120 each, making 240 total. It would only take us 5-6 years to "purchase" a complete set within our budget.
Most dive shops offer "annual" maintenance service for BCDs. FYI, I've never had any of my BCDs serviced by a dive shop. With the proper post-dive fresh water rinsing, this shouldn't really be necessary. After many dives, you may have to service the power inflater. This can be a DIY job or you can pay the shop to do it.Regardless, I understand what you meant. Assuming we bought ALL gear, how much could we expect in annual maintenance charges?
Regs are another matter. Some manufacturers have a free-overhaul-parts-for-life policy, provided that the owner gets the reg serviced at the recommended manufacturer-specified intervals (every year or every other year). Excluding the price of parts, servicing for a first stage + two second stages + analog SPG (HP spool) ranges from $50 - $125. Shop around for the best price and the best quality work. After getting the reg serviced, I'd recommend doing a handful of "test" dives before really trusting the reg setup. It's been my experience that regs tend to have issues right after servicing. Weird, huh?

Snorkels are definitely not necessary for diving. I only use my snorkel when I...go snorkeling. It's a happy coincidence that many places that feature diving also offer snorkeling opportunities. That's why I take my snorkel with me while on a dive vacation. Some people like to use their snorkel while kicking out to a dive site or if surface conditions are rough.Are snorkels and wetsuits really necessary? We dove in Jamaica in shorts and tees and I thought it was fine.
Wetsuits are not necessary either. However, as you gain experience, you'll find that your movements underwater become more efficient. This means that you aren't burning up all of that energy (non-stop kicking, sculling with hands, etc.) which seems to make people feel "warmer." More experienced divers tend to have longer bottom times and do more repetitive dives. This increases the likelihood that you'll get cold. Wearing a wetsuit keeps you warm and provides some protection from cuts/scrapes/stings.
