I hesitate to point it out but Fooser & Pal uses it. Do a search for their website. Back in Feb/March, the last time I was involved with the service, he was in a losing streak.
Another guru you may take a look at is Ricochet Trading: http://www.ricochettrading.net/ They provide guru signals across the SR Network.
From what I know Ricochet is currently live trading with Spike. I'm not sure about their ability to trade with other brokers, nonetheless, best thing to do is to check with them directly.
