Two-Way Dictionary

A few days ago, I received an e-mail from someone in Canada who is planning to teach an Esperanto course to 45 students.
He was looking for a good, inexpensive, two-way English and Esperanto dictionary.

I was somewhat ashamed to admit that Esperanto-USA does not have such a dictionary.
The Beginner's Compact Dictionary by P. V. RANGANAYAKULU is so fraught with errors that the author has decided not to reprint it.
The Pocket Esperanto dictionary by MCLINEN costs almost $25.00 and Don Harlow's comment is 'Use with some care'.
BENSON's Dictionary is only one-way, and the Mini-Dictionary by GRIMLEY EVANS is too limited.
The Teach Yourself Dictionary is no longer in print.

I started to think about how a useful two-way dictionary for beginners would be organized, and I came to the following conclusions.

The English-Esperanto section would contain minimal entries, referring only to the Esperanto root word.
Example: pack - pak'

Derived English words like 'Package' would not be listed in the English-Esperanto section, but would be shown in the Esperanto section.

If an English word has multiple Esperanto translations, multiple roots would be shown.
Example: interest - interes', interez'

Words which have a myriad of meanings such as 'get' and 'set' would point to other English words whenever possible.
Example: get - -> receive, acquire, attain, convince, [there would be many entries here]

Words in English that are translated into Esperanto using the mal prefix would point to the root Esperanto word
Example: dark - lum', hel', fi' ->obscure

The Esperanto-English section would have entries similar to that of Butler or Milledge - including root category, transitivity, the appropriate preposition to use with a specific verb, examples of affixes where the meaning is not obvious, etc.
