....and you will get a multitude of opinions all of them ready to confuse you.
The trouble with the net is opinions....thousands of em. Who says the silvia has a problem with the element when left on for a period? I would say those most likely to leave it on for a period ***in steam mode***, where it should not be left. Train yourself not to do things your shouldnt* ;) and you probably wont have a problem. But if your budget stretches way further than that, why bother with it when you can go to a micro sized commercial design machine ( as in HX).
There is a great Unico Splendor HX machine in the "for sale" section of this site. Better go there quick for the price is good. Buy a quality grinder, and enjoy a step up in a better quality of machine & grinder that will elevate your coffee experience to a place where you havent been yet.
When you go from the combi to a far better quality of machine....why even think about* a PID at this point? Again...too much internet influence and "research" ;)!
Finally, DO NOT rehouse the girnder from the combi. It belongs wherever the rest of the combi goes. You will not recognize the coffee when you go to a better standard of setup.
If you want to purchase new equipment and are willing to trust a long standing trader and the very first CS commercial site sponsor, give me a call.
Hope this helps.
