As somebody said before, They have upgraded the motor and such. I brought my first CPP2 in 1983. I then brought another, humidity killed one board. I still have one to this day. It is like brand new, its only had one new pump, two new motors, a couple of reworks on the board and I made a handle to overcome the lift issue with 3000 drums. All jokes a side it is built well and is designed practically. I can only see the advances in electronics to be a blessing to the new machine. I would ensure you would have good ventilation to contribute to the longevity of the components. I will be getting one for sure.
