I wonder if the LFS around you guys sell much. The ones around here say that they don't sell more than a few panels a month... more of a whim purchase. Almost everybody who is new will price shop online anymore.
Of the good LFS around here does sell hundreds of ATI and MH bulbs and a handful of replacement ballasts a month to the legacy folks - he keeps it close to online prices which is cool since shipping bulbs is not cheap anymore. I think that most folks will support the local guy if they are cool and are close to online prices.
About the LFS - they use what they need to so sell goods. They rarely think long term or about keeping a coral. The rare shop will have a really nice display that has entirely different equipment on it than their frag/coral flats which usually are blue/black lit to sell some so-so corals with the extra pop. Fish at 1.018, 100% copper usage, temp at 82, corals under blues only, clams under blues only (ouch!)... none of these are good long-term strategies, but they work OK for the LFS. I would caution anybody to look to a LFS for much guidance. If you can find a good hobbyist that happens to work at a LFS, then that is awesome - of the dozen or twenty stores in Colorado, I know of two that have this.
