I was buying the .11s last week, and have been averaging down in the .07s recently. I think anything under .10 is an easy double IMO. I also think it goes higher though, but let's take things one step at a time. There is only around 15 million oustanding here, so eventually that float is going to dry up.
My post is only my opinion, I recommend you always do your own DD! I am not a licensed broker or a professional by any means, so take what I say as entertainment value at best.
