Century welders are sold at NORTHERNTOOL.COM. See below for full list:

The bigger Centruy's are 'semi-pro' welders as they have many of the features of the miller/hobart/lincoln's but are less costly at the time. Things may have changed since Lincoln bought them out.
Whatever you do, do NOT buy a gassless one. Get one with the provisions for a gas solenoid. Makes for easier and nicer welds.
