To add another perspective to the conversation... my next tank looks like its going to cost between 7 and 10 thousand, just for the glass box(a really, really nice one). I'm pretty sure I would'nt hesitate a second to spend a few hundred to keep it clean without damaging it. What its worth is not necessarily a sum of its parts, but the value to target consumer. Truth is that I would spend 500+ if it was guaranteed to not scratch the glass, and has a record to back it up. I have the tunze, multiple flippers, used razor blades, blades on a stick- they all have scratched my current tank. This is what's stopping me from buying/ starting the next tank, I need to finish learning how to clean glass without damaging it.(Accepting tips/ recommendations/suggestions.PLEASE) that said..., if a company preys on that for a one time purchase, with a subpar product, they won't last. However if they meet and exceed expectations of their customers, they can charge whatever they want. If you think it's too high, its not for you. Nobody's forcing anyone to buy anything. Its like if I tell someone its $2000 to fix the a/c on their mercades, and they agree, but someone else quoted 1000$. As long as install the promised parts, it works, and i back up my work- its not ripping anyone off. They had a choice. Sometimes you pay for the headaches you avoid.
