You need to do some coding, if you can  then following code work for you.

Now let ‘s copy:  

    app/code/core/Mage/Catalog/Block/Product/List/Toolbar.php

to:  

    app/code/local/Mage/Catalog/Block/Product/List/Toolbar.php

(*create a new directory if it is not exists*).

Open new file and look at these lines of code in around line 232:

    if ($this->getCurrentOrder()) {
        $this->_collection->setOrder($this->getCurrentOrder(), $this->getCurrentDirection());
    }

Now, replace with these lines:

    if ($this->getCurrentOrder()) {
        if(($this->getCurrentOrder())=='position'){
            $this->_collection->setOrder('entity_id','desc');
        }
        else {
            $this->_collection->setOrder($this->getCurrentOrder(),$this->getCurrentDirection());
        }
    }

That ‘s all, now remember to clear all cache and reindex too see the magic.
