Have the dropper it is fantastic and worth the money, the derailleur is $700 and I break one or two a year because of sticks getting sucked up, not to mention the torque just chews up chains and cassettes about every 750 miles. I've got Di2 and have only broken one in about 3000 miles just love it, but they are only $190 USD.
Warm Regards

LMK where you're finding DI2 rear derailleurs for $180!
