Whats the best way to lookup data in Field Collections with EFQ?

I have a Field Collection with a couple of fields set to a host entity that contains a table of pricing information. When new prices are received from a third party service, I would like to query against the incoming option, locate it, and update its price.

Heres what I have been trying ($this->entity_id is a host entity ID, the other two $this values are assigned when looping the data):

<?php
$query
= new EntityFieldQuery;
       
$query->entityCondition('entity_type', 'field_collection_item')
            ->
entityCondition('bundle', 'field_trinkets')
            ->
entityCondition('entity_id', $this->entity_id);
        if (isset(
$this->trinket_option)) {
           
$query->fieldCondition('field_trinket_option', 'value', $this->trinket_option, '=');
        }
        if (isset(
$this->trinket_price)) {
           
$query->fieldCondition('field_trinket_price', 'value', $this->trinket_price, '=');
        }
               
$trinket_record = $query->execute();
        if (
$trinket_record) {
           
$trinket_record = end(entity_load('field_collection_item', array_keys($trinket_record['field_collection_item'])));
            return
$trinket_record;
        } else {
            return
FALSE;
        }
?>

Either way, no records are ever found when there should be matches most of the time. What am I missing?

Any suggestions?

The answer (for me, at least) is found here: http://drupal.org/node/1353926 (especially the comments).

Bumping this, but in relation to EFQ Views. The Field Collection is only available as an entire entity, and the fields contained within can't be hooked/manipulated by the view.
