Magento collection filtered

Here’s a simple setup for a product collection with the following filters used in most of my modules, ideal for things like product feeds etc.

It has the following filters

– By Store
– Must have price > 0
– Must cost > 0
– Only simple products
– Visible either Catalog,Search or Both

$visibility = array(
    Mage_Catalog_Model_Product_Visibility::VISIBILITY_BOTH,
    Mage_Catalog_Model_Product_Visibility::VISIBILITY_IN_CATALOG,
    Mage_Catalog_Model_Product_Visibility::VISIBILITY_IN_SEARCH
);

$storeId = 1;

$collection = Mage::getResourceModel('catalog/product_collection');
$collection->getEntity()->setStoreId($storeId);

// Reset the select.
$collection->getSelect()->reset();

// Update table name.
$reflectionMethod = new ReflectionMethod($collection, '_initSelect');
$reflectionMethod->setAccessible(true);
$reflectionMethod->invoke($collection);

$collection
 ->addAttributeToSelect('sku')
 ->addAttributeToSelect('name')
 ->addAttributeToSelect('description')
 ->addAttributeToSelect('small_image')
 ->addAttributeToSelect('manufacturer')
 ->addAttributeToSelect('msrp')
 ->addAttributeToFilter('visibility', $visibility)
 ->addAttributeToFilter('status', '1')
 ->addAttributeToFilter('type_id', array('eq' => 'simple'))
 ->addFinalPrice()
 ->setPageSize(900000)
 ->setCurPage(1);
