If it was me I'd lean more towards the Izzo Duetto over the vibe' DD mainly because Duetto brew boiler target temperature adjusts in 1F increments vs 1C (1.8F) on the vibe'.
NOTES: 1. The Vibiemme PID espresso machine can display in Fahrenheit or Celsius, but in Celsius increments - meaning every so many degrees Fahrenheit it will skip one degree Fahrenheit . For example, when in PID program mode, the display will show 217, 219, 220, 222 when programming to a higher temperature.
vibe' DD can display in F
but sets the target temp in C.
While I'd prefer 0.1F brew boiler target temp' adjustment 1F is better than 1.8F!
