Yer I've got one that works with a sub directory. Infact any of the mods should work in a subdirectory, all you have to do is open up the .php file, modify the path to config.php and then in the embed code point it to the .swf / .php as you would normal, and this should get it working for you.

Try this first before you buy anything else, and let me know if you need any help installing via sub-directory.

Hope this helps,
