If you like to play with group temp and pressure the expobar minore is one option
Group head pressure can be adjusted easily by sliding out the drip tray where you have access to the OPV all you need is a flat head screw driver, its a 30 second job
Then you have the PID for your temp
Its a double boiler and you have the option of turning off the steam boiler if only drinking short blacks,
Lots of options .......
