Hi guys - recently picked up a used ECM botticelli ii t from the bay of evil for $200. A bit of a risk (if i waste $200 on scrap metal then so be it) but it is to be used as a work machine (for me only) i have a bezzera magica (good quality HX machine) for home use so like to think i am no stranger to a reasonable coffee. I have an old sunbeam em0480 to pair it with at work but was just wondering if there is anything i should do beyond a clean up, descale and backflush prior to using. I was also interested in whether there were any common problems i should know about and whether i should consider a PID... is this necessary/beneficial for a single boiler like this.

Appreciate any suggestions
