i recently upgraded my commercial machine to a san remo roma tcs 3 gruppi which is an awesome bit of kit. for home use i have a san remo treviso lx with rotary pump and a sr80 grinder which i will be honest makes a good coffee but nothing like its bigger blacker badder brother! i think overkill is in the eye of the beholder if you take something seriously and with passion nothing wrong with being carried away!
