Lexmark took over IBM typewriter production as IBM started producing the Personal computers in the 1980s and production was discontinued just before the turn of the century. A rebuilt IBM typewriter is still the most popular typewriter even though new typewriters are being manufactured by Nakajima. Supplies and parts are still available and should be plentiful for the next 25 years. An IBM typewriter rebuilt by Around The Office should give you many years of service and EXTENDED SERVICE polices are provided by EBS Hard to Find Office Supplies & Around The Office.
