As testament to their longevity, and that of the equipment which incorporated them, as of 2006[update] several suppliers still provide common Nixie tube types as replacement parts, new in original packaging.[citation needed] Equipment with Nixie-tube displays in excellent working condition is still plentiful, though much of it has been in frequent use for 30–40 years or more. Such items can easily be found as surplus and obtained at very little expense. In the former Soviet Union, Nixies were still being manufactured in volume in the 1980s, so Russian and Eastern European Nixies are still available.
