Considering how much outcry there is, I would think you'd have everything you need to decide on whether or not if you want to invest with BFL.  I've personally been scammed by them.  So my answer is yes.  If they scam you or not, I guess that's between you and BFL.  Considering that 98% of the people who ordered last year have not received their order yet, it doesn't look favorable for anyone new to jump into the pit.
