Really depends on if you want it to have a variable speed water pump. I supposed the fab cost for outlets on twins could add up but for bottom mount single, the plumbing is simple and minimal since my compressor outlet already points up. The only substantial cost is the actual cooler. The pump and heat exchanger will only total about $500. That and mine isn’t a daily so minimal miles driven so I’ll be running the water pump full tilt. I spoke to Davies Craig and they actually recommended this over any kind of PWM control.
