Cool dropdown menus: how to integrate in Drupal?

Hi all. I think many drupal developers have had a problem on how to integrate high-quality menus, including dropdown into Drupal menus system.
Nowdays, (as i googleit and search drupal.org) all we have only one third-party menu implementation into Drupal's - it's well known Superfish menu (or suckerfish) http://users.tpg.com.au/j_birch/plugins/superfish/

Here is the tutorial how to integrate superfish into your drupal 6 (site is not my)

BUT, i see that there is no rich menu animate options, prestyled css with different styles, so i started search on how to integrate css, js - generated menus. Here are some examples of really cool menu systems, and YOU CAN GENERATE ANY STYLE YOU WANT with this menu generators, that's cool, in not it?

(check out them - its cool)

So, i want to ask, who can help with integration of these menus?
The problem is that you need to get drupal menu into the strikt ul li structure, i foun how to make this with the following code:

$my_menu = menu_tree('primary-links');//load the formatted menu_tree from drupal
$my_menu = str_replace("leaf", "", $my_menu );//strip the leaf class
$my_menu = str_replace("active-trail", "", $my_menu );//strip the active trail class
$my_menu = str_replace("menu", "", $my_menu );//strip the menu class
$my_menu = str_replace("active", "", $my_menu );//strip the active class
$my_menu = str_replace("expanded", "", $my_menu );//strip the expanded class
$my_menu = str_replace(" first", "", $my_menu );//strip the first tags (w and w/o space)
$my_menu = str_replace("first", "", $my_menu );//strip the first tags (w and w/o space)
$my_menu = str_replace(" last", "", $my_menu );//strip the last tags (w and w/o space)
$my_menu = str_replace("last", "", $my_menu );//strip the last tags (w and w/o space)
$my_menu = str_replace(" class=\"\"", "", $my_menu );//strip the now empty class attribute and quotes
$my_menu = "

" . substr($my_menu, 4, strlen($my_menu));//replace the
with a ul tag thats classed for Superfish

print ($my_menu);

(insert this code into page.tpl.php instead of navigation print theme('links', $primary_links, array('class' => 'links primary-links'))) http://www.drupal.ru/node/36709
this is useful for superfish as you see in comments

So have you an idea how to implement generated menus?
