You can use my directory as Google Bot is crawling at most times of the day. Please see my signature. I offer very fast reviews and deep link/multiple URL listing options as well. Most good directories will get you indexed fast because your link will appear on the "new sites" page.
Not younger than 4 years can be though for you actually, unless someone converted their old domain into a directory. Have a check on the dirs in my siggy, use coupon code if interested.
