Best to call a template within a template Magento - magento

Question

So I have been working on a Magento module that hides the price when the user is not logged in. I got it working thanks to #AlanStorm but I just want to make sure it I'm going for the best approach.
What I did is setting a different template for the *catalog_product_price_template* block and from there I did all the logic
<?php $_message = Mage::getStoreConfig('catalog/pricehideconfig/title');
$_enabled = Mage::getStoreConfig('catalog/pricehideconfig/active');
$_current_template = Mage::getBaseDir('design')
. '/frontend/'
. Mage::getSingleton('core/design_package')->getPackageName() . '/'
. Mage::getSingleton('core/design_package')->getTheme('frontend') .'/'
. 'template/catalog/product/price.phtml';
$_default_template = Mage::getBaseDir('design') . '/frontend/base/default/template/catalog/product/price.phtml';
?>
<p>
<?php if ( $_enabled && !($this->helper('customer')->isLoggedIn()) ) { ?>
<?php echo $_message; ?>
<?php } else {
if (file_exists($_current_template)){
include $_current_template;
} else{
include $_default_template;
}
} ?>
</p>
However, two parts seems really unnatural
Calling the 'original' or default template code for the price doesnt feel right, does Magento provides any function to do this, call the default template within a template, while checking if the template exists in the current package and then revert back to the default if none?
I think the template should be used for presentation only, so the variables assignment should be moved to a block instead, but i can't really do that since I'm just setting the template and not extending the *Mage_Catalog_Block_Product_Price_Template*

I don't really understand the code above !!
if you want to hide price from non-logged in customers the easiest and best way i have used is :
The Module will be Only one Block and the config.xml
Extend - Rewrite class Mage_Catalog_Block_Product_Price
class Namespame_ModuleName_Block_Product_Price extends Mage_Catalog_Block_Product_Price
{
// and Override _toHtml Function to be
protected function _toHtml()
{
if(!$this->helper('customer')->isLoggedIn()){
$this->getProduct()->setCanShowPrice(false);
}
if (!$this->getProduct() || $this->getProduct()->getCanShowPrice() === false) {
return '';
}
return parent::_toHtml();
}
}
This works perfectly without adding more codes to view/template/layout !
If you still want to set Template you can do it also as :
class Namespame_ModuleName_Block_Product_Price extends Mage_Catalog_Block_Product_Price
{
// and Override _toHtml Function to be
protected function _toHtml()
{
if(!$this->helper('customer')->isLoggedIn()){
$this->setTemplate('mymodule/price_template.phtml');
}
if (!$this->getProduct() || $this->getProduct()->getCanShowPrice() === false) {
return '';
}
return parent::_toHtml();
}
}
Thanks
