This thread is making me bullish. OP asks for upper and lower prices that would signal further movement in either direction and 95% of the posts are about the lower price. I don't think we're going much lower but I would call $150 an important level on the low end. On the higher end, I think we get to $400 or $500 before the public notices again. Hysteria starts 10-20% above the previous ATH.
