I'm not sure of what the "Blue Book" value on such a machine is, but I can tell you that this is an extremely rare bird. I saw one badly corroded with its motor missing, and the shop owner wanted $75 for it. Burroughs is a rare typewriter anyway. I fixed one--the totally manual one made in 1931. They started with the "electric" version in 1932. Don't know how long they made either one. Long story short: See a burroughs--Get it if you can afford it. It may not make "The Antiques Road Show," but you'll definitely have an interesting conversation piece--and playtoy.
