Ninja Coffee Bar Single-Serve System (CF111/CF112) $79.99 - Amazon
Has been a bit cheaper if you got lucky with the Wal-mart clearance sale or Kohl's Card coupon stacking, but the lowest I have seen without jumping through hoops. Model CF111 is $79.99 shipped and CF112 $83.99 shipped. Only difference is the CF112 comes with the hot/cold XL tumbler. I would suggest skipping the Ninja tumbler anyway and grabbing a 32oz Ozark Trail Stainless Tumbler for $5. Can also add a 2-year Extended Warranty for $2.51.
