Update:
Just received the 2. Helios-Preisser / made in Germany/ square straight edge DIN 874/2 1000mm / 66 euro with shipping. I am impressed. Perfectly ground and polished with no marks, katana -like. Great deal. Came just with cardboard case but well protected in big cardboard box. I could not be more happy, especially for the money i spend and the quality i received. Made in Germany + Din 874= good choice. I am quite happy i spend so much time making a choice and did not rush to the shady ones. thats all for now. Hope that all this experience will convince DIY guys that its worth spending some money on precise instruments that don't cost arm and leg.
