Captain, you make very good points however I have to disagree with your conclusions. I do not have a lot of disposable cash which allows me to buy the best of everything. Yet, through my efforts of being frugal, I am still able to keep a very nice display tank. Matter of fact, I am about to upgrade that 45 to a 125.
I think it would amaze you if you knew just how much I have spent in doing this. When it came to deciding on lighting for this new tank, my first inclination was to build my own DIY T5 set up similar to the one I did for my 45. But, through research and a little hard work on my part, I am getting 3 good Dimmable LED fixtures which should work nice. As part of the group buy I put together for these fixtures, I am paying $235 each. For now, I won't have a controller to do all the fancy sunrises, sunsets, etc. but for $30 I can build manual control for them. Then one day, if I have a chance to pick up a controller, my fixtures will be ready for it. Had I gone with the T5 set up, and done timely lamp changes, I would spend the same amount after only a few lamp changes.
Please don't take this the wrong way. I see many times where people who have extra money to be able to participate in this hobby in a way we all would like, think that it is a waste for those who's incomes may not allow that. In my opinion, that is wrong. People on tight budgets still need to have things in life they can enjoy. If life is spent only paying the bills, what good is it? Could I use the money I put into this hobby more wisely? Sure I could.
