I've been screwed over really bad by the poor predictions made by Butterfly Labs - I didn't feel right passing that on so yes, I'm basically telling people that if the pay what I'm asking, they may lose money - assuming everything continues as it has been for the last 2 weeks.  That said, I'm taking a risk as well and (quite honestly) I'm happy to keep mining with it knowing that I didn't screw some poor sap "newbie" out of his/her hard earned money...  Call me crazy...
