I have been planning to open a typewriter shop in the Seattle metro area for a while--I now have a both at the Aurora Antique Pavilion, 24111 Highway 99, Edmonds, WA (Across Highway 104 from Aurora Village, above the Burlington Coat Factory). I specialize in reconditioned portable typewriters, which have been serviced to full working order (unless otherwise marked).
Bohn Contex with instructions (glued to bottom), $40, portable typewriters $60-150, Universal typewriter case $10, the joys of installing paneling, priceless.
