I think it's really important to have non invasive equipment. Expense is of corse a different matter. We all can afford only what we can afford. but as a visual experience , which is what an Aquascape is, it is of corse important that it not be marred by huge unattractive heaters and other unsightly appendages. For myself I can;t stand seeing huge heaters and other stuff in an Aqua scape.I look at them as works of art and am completely distracted by ugly equipment. It disrupts the image. Is my set up exactly were I want it to be? Nope. Not yet, This stuff gets really pricey. And we all have our priority's. Mine have been spent on glass lily pipes and external filter and heaters but I would still like an ADA stand and..well still a lot more then I am currently willing to spend. But we all have our priorities/ yours might be on such gadgets as automatic water changers and pressure regulators and solenoid valves for your co2. While I still use the less expensive DIY yeast mix. So as they say beauty as in all art- is in the eye of the beholder. And part of the fun of this hobby is it's on going quest to "get it right". we all have our opinions and that is just my own humble thought. peace and happy Aquascaping to all.
