I have to admit the price for the German controllers are beyond Pluto. That is why I wanted to have my own HV controllers done to try and bring the prices down. I'm not sure why those controllers are so expensive. If you do the math on how much the components cost, people start thinking twice. I understand if an engineer that developed a great software charges a lot, but if they already have a good software and pretty much paid for all the developing cost, they should bring the price down. I for example don't sell electronic components for everyone, because I wouldn't make much profit. Now when I sell to Felxtronics in Brasil, I'm happy with the profit that I got from selling high quantities. Schulze is really missing out on profits from high quantity. I like the Schulze, BK, Kontronik and Actronic, but they could make more money if they priced their products the right way and sell higher quantities.
