Echo different text if specific product is in cart or not

I have a problem with my checkout cart. I need to check out, if a particular product (with the ID 1) is already in the cart. If it is inside, I want to show Text 1. If it is NOT inside, I want to show Text 2.

Here is my code, I came so far until now:

    <?php
$items = Mage::getSingleton('checkout/session')->getQuote()->getAllItems();
$found = false;
foreach ($items as $item) {
    if ($item->getProductId() == 1){
        $found = true;
        echo "Text 1";
        break;
    } 
}
?>

Sorry for my bad english, I´m from Germany. Maybe anyone can help? Thank you
