It seems some online suppliers are selling out their remaining Driverack Px's with a measurement mic for $149 and free shipping. Guitar Center is sold out when I looked, but American Musical Supply still has them. I just ordered one. PE has them at $299 and I didn't bother calling to see if they would price match.
