LOL...thanks for all the replies and tips (wish I could have replied earlier, but SB is blocked at work). I ordered Jablonski's book "Doing it Right: Fundamentals of better diving", it arrived on my desk by Thursday, and I am already half way through it. Definitely a motivating piece for getting experience and mastering the basics rather than rushing on with sloppy habits.
Actually, as a first-timer DIR wannabe, I am looking for holistic advice, not just on gear or training, but on experience / mindset / things to keep in mind while practicing / setting goals / interacting with buddies, etc. I certainly can understand why people get obsessed with the gear aspect; it is much less fun to regret a piece of gear that doesn't really optimize your dive experience, while even bad experience or training can be learned from and doesn't take up space in one's apartment...
