Firstly Id encourage you to do a search on this site. *Hit the search button above. Make sure you change the search range as its set for one week as a default.
Note that the Lelit Combi, Nemox Dell Opera, Mokita Combi and Quaha Napoletana are all essentially the same machine. *Only the first 2 are current models.
There is a handy article on an Australian website which I won’t supply a link to as its a non-sponsor commercial site. *If you google lelit silvia comparison youll find it easily. *The Pullman website also has some very useful information on the Quaha.
The Combi & the Silvia are fundamentally similar machines although some of the Silvias components are slightly better quality. *Others have also mentioned that the finish of the Silvia is also slightly better. *They are priced similarly but with the Lelit you effectively get a ‘free’ $300 grinder built into the machine.
For $800 from Talk Coffee, the Lelit is definitely a bargain. *Its a great entry level quality espresso machine thats built to last. *
I don’t think having a built-in grinder would affect servicing too much. *The grinder is pretty easy to access. *On the downside, you can’t upgrade individual components. *As an example, I recently compared shots on my Quaha using the built-in Lux grinder with a Compak K3 Elite. *The Compak gave far superior results. *I guess I could use the built-in grinder for decaf!
I have not used a Silvia but it certainly seems to be the gold standard for entry into quality espresso. *There is a lot of information out there on how to PID them. *I assume you could also add a PID to a Lelit but it would be harder to find a guide for that if you wanted to do it yourself (and had little technical nous like me).
Bottom line…the Lelit will give you excellent results for many years at a bargain price.
The Silvia is a slightly better machine that would most likely give you similar results with a similar stand alone grinder. *Combine with a Rocky, you’re looking at an extra ~$400 compared to the Lelit.
Both have reasonably good resale value.
