OnePlanOnHouzz - We do Leicht, Hacker and Stoneham.
I have looked at pricing and Leicht is about 5% more and vastly better. Hacker Classic I would say is broadly comparable and about 10-15% cheaper. Hacker Systemat would be similar money and better too.
In the interest of fairness, Schuller C1 would be a good Hacker Classic alternative. Pronorm should be similar money to Nolte and much more flexible.
I'm familiar with Hacker ! I regularly design / do CAD work with Classic, Systemat and Emotion ranges ! Great product !! Used to do freelance design with Nolte for a studio in London - don't get involved on the pricing - so good to hear the comparisons !!
