Usage

<?php

// ...

$fooTable = new DbTable_Foo();
$fooTable->insertOrUpdate(array(
    'field_1' => 'value',
    'field_2' => new Zend_Db_Expr('NOW()'),
), array(
    'field_3' => 'other value',
    'field_4' => new Zend_Db_Expr('NOW()'),
));

@mattparker - You're right, my apologies. I've since fixed that but never came back to update this Gist.

Nice job!
