I'm a newbie, but here's some stuff I learned while getting my gear.
1. Don't just go and buy gear that people suggest (or that's cheap or that your local dive shop has). Try it out (through rentals at different dive shops). Personal preferences are vastly different.
2. Do your research...a lot. ScubaBoard is a great site for that. I also like
Scuba Gear Reports and the user reviews on LeisurePro.
- I kind of wish I had waited before getting a lot of stuff (e.g., I would have preferred a back inflation now rather than a jacket
BCD; using non-split fins but bought splits; prefer a self-donning drysuit that's a bit more pricey), but I got it often because of pressure and price.
3. Don't underestimate used gear.
- If I had waited a short while or done research on Craigslist, UsedVictoria (for Victoria), I could have gotten so much better deals for great gear. While buying my accessories (after I had already bought the
BCD/Regs), I found so many great deals for nearly new gear from people quitting scuba. People quit all the time with all their gear.
- Some of this gear is nearly top-of-the-line (or at least pretty good) but for half the costs of retail/online.
4. Consider buying the essentials from a trusted local dive shop (i.e., probably only the regulator/octo set)
- This helps build a relationship, AND they know how to fix it well. It'll cost a bit more, though.
Let me make this clear. This is the newbie perspective on things. Use these as maybe a guideline.
As for drysuits, I use a Bare Nex-Gen Pro, which I love, except for the rear entry. You can get that for $1200, but I got a sweet deal. I've used the White's Fusion. Impeccable front-entry suit, but $2300.
A great starting point is ScubaBoard or just asking your local dive shop about the gear (while being wary about them trying to sell you stuff).
