I had posted a thread showing how everything was made- by hand. The markup on Tunze stuff is actually much lower percentage wise than what is on a $30 powerhead. With a 75gal tank you would only need a 220.54 magnet- $25. For a powerhead you would need a 7400/2 and a single controller. The flow is equal to 4 maxijets and with a wavemaker which is at best half the quality because it is only off and on that is a $200 set, the Tunze set is just under $300 and will last twice as long and uses 1/3 the electricity. If you really give it more than a glance over it is very reasonably priced. The $200 magnet is cheaper than a competing magnavore for glass of equal thickness. But again, our products are hand made in a first world country with first world labor prices and standards- we can't torture people in a third world country, making them breathe in toxic adhesives and fumes and send them home with six bucks for a days labor like the cheap competition. We have to meet German occupational standards which means low VOC adhesives, fume hoods, labor laws, minimum wages, paid vacations, pregnancy and sick leave, etc. If you add the quality, the unique features of computerized low voltage control, the pumps and all products are very reasonably priced and you will save money in the long haul on electricity and the life span of the product. We do also make standard synchronous powerheads and they are well under $200, the expensive units are low voltage electronic models.
