Has anyone tried...

Just wondering if anyone has tried to use their SB-400 off camera with an optical trigger. I have a SB-400 (should be returned to me from an extended loan soon) and am finding the need for more off camera light, so I am wondering if it anyone knows if this will work. I figure a cheap optical trigger will be more cost effective than another SB-800 (I am not going to buy any more SB-600s).
Anyone tried? Anyone game to try?
Cheers
