Synonym text list of common English words

I need a large text list of common English words mostly adjectives with its corresponding synonym. The list should be in some kind of text delimited format where for each word, there is just ONE matching synonym like this:

big large
blank empty
broad wide
center middle
cunning clever

The delimiter can be anything.

Or I can use a database that has been formatted in the same 1 word to 1 synonym and can easily and directly be imported into SQL 2000.

I don't want to pay  more than $200 or so for the list, free of course is best.  I spent two hours looking for such a text list but had to give up.  Please don't give me a link unless you know it has what I've outlined here.

Note that I've already look at wordnet.princeton.edu but there is no such list and I'm not experienced enough to even try to convert or port their .data file to sql.  I tried and gave up so, let's please not go there, or any similar place. Let's keep this simple and that's why a text file is appealing.

But if it IS a database that has more than one synonym then I can use it only if I can separate the synonym list easily, so that the first synonym is used by default, or I can reformat in MS Word, or that multiple synonyms reside in separate database columns.
