I don't have such a set myself, but I've learned that they sold this and the 500 together as a complete set, one for the office, one to travel with. Logical, they have the same scales. Like the katana and wakazashi of the samurai, two rules are better than one.

This model was on the manifest for several Apollo missions as a backup computer. Imagine!
