To a degree I agree. The lights that have storm modes, wifi, etc are going to be much more complex than a simple shop light. I expect those to be 2 or 3 times the price. I have no problem with that.
That said the more expensive lights are often made in the same Chinese factory on the same machinery as the LED pucks you get at big box stores, not to mention they are often made with the same materials.
The problem is not limited to lighting however. Dry goods are ridiculously expensive. Someone mentioned algae scrapers being ridiculously priced. When I first set my tank up I remember the ridiculously high prices for flake food. I compared the ingredients for freshwater flake to saltwater flake and they are almost exactly the same. Yet one is twice the price of the other.
Even coral is ridiculously priced. Is a 1 inch frag of pulsing xenia REALLY worth $130? Of course not. As long as people are willing to pay ridiculous prices they will only go up.
We are our only line of defense. The more we help each other the better off we all are. I see many people here helping others out. That is one of the biggest reasons I love R2R.
