My wife and I dive the Atomic Ultra, and SeaVision masks, respectively. You're not going to find those at SportMart (or K-Mart, or Walmart, etc.).
I think masks are to diving what speakers are to a sound system... It's not necessarily the most technical piece, but it's ultimately what you see (or hear), that counts. (Of course, durability, fit, and finish are issues, as well).
As for regs, BCs, computers... I wouldn't consider anywhere but an LDS.
P.S. I use both purge and non-purge SeaVisions... they're both great, and problem-free. (And I have many more than 9 dives, at depths well over 85 feet, on the purge model).
