If premium quality coffee is your thing, you should check out the Evoluzione V2 from Rocket Espresso Evoluzione.
This machine offers the versatility of using the water reservoir supply or a direct water connection operated by a control switch. It has a full commercial rotary pump as opposed to a vibration pump. The gadget-boiler utilises thick, lead free brass end plates and an insulated boiler for energy saving and increased thermal stability.
Apart from producing fine coffee, it is a beautiful gadget and also a kitchen-trophy. It costs $2 100 but it is money well spent as the V2 will redefine coffee as you know it.
