The benefits of buying your Heidenhain BE135 from Monitech are substantial. We offer an upgrade over the OEM; the CRT that your unit currently has is very old technology, nearing the end of its life cycle. Our LCD monitors are current technology with a very long life expectancy; over 50 000 hours. We offer our newer technology at a much lower cost than the OEM charges for their aging displays. In addition to the monetary savings and enhanced products, we have very quick lead times; we can often send out the product the same day an order is placed!
