I don't mean to be too negative, but I have looked at these guys before. Some negatives:
--Some huge losses on signals (see their history)
--They are not timertrac'd
--I scratch my head when a service uses neon colors for its web site. Sounds like a small thing, but if they can't even build a web site that doesn't look like a circus, I wonder about them.
If you have patience and make money though, I'd say stick with it.
