I have tried Triocaine. For me, it didn't work as well as emla, it numbed faster but didn't numb as intensely. A friend of mine said it worked better than emla for her. One might have to try it to see which works better for them.
Incidentally, a while back Dr. Numb was advertised in a spam post here on Hairtell (James made some rather amusing changes to the post.) Whether it was them or a third party I don't know (but I bet James can tell us.)
