Stay away from hyphens, but if you must get hyphenated names then at least make sure they are in a place where they belong like separating two words or between two parts of a word that normally have a space. Such as free-ringtones.com or something like new-york.com. L-L.com is also starting to pick up and L-L-L.com is too although I dont like them. Definitely dont get any L-LLL.com.
