This works perfectly

If you know that the collection just has one item then you could simply use $someCollection->getFirstItem(). This will give you the first and in your case only item. You can then continue to use the getSomeField() etc on this object.

A second option is possible to use ->load($attribute_value, 'attribute_code'); on the object but this can add overhead if the table is of a large size.

Get your collection like this.

$productsCollection = Mage::getModel('catalog/product')->getCollection()->addAttributeToSelect('customizableonly');

And here is an other way of updating all products at once so you don't have to call saveAttribute 2k times.
From what I understand, you want to set the value for customizableonly to 0 for all the products that don't have that value.
Here goes:

$toUpdate = array();
foreach ($productsCollection as $_product) {
    if (is_null($_product->getCustomizableonly())) {
        //remember the id for update
        $toUpdate[] = $_product->getId();
    }
}

//update all products
Mage::getSingleton('catalog/product_action')->updateAttributes($toUpdate, array('customizableonly'=>0), 0);

This should get you a boost in speed.
