I’ve been using Sachs Ergo 8-speed brifters for over 20 years and love them. They are very clean shifting and have been quite reliable for me. I’ve probably rebuilt 4 or 5 of them in that time and over 40,000 miles. Yes, the clicks in the front (left side) brifters allow double or triple FD’s, with very simple trimming.
Campy “g-springs” are the most common wear part. They are readily available inexpensively. I’ve never had a cracked spring carrier (knock on wood!), but have spares if I need them.
I’ve used and like the Ergo instructions in Leonard Zinn’s manuals, which are much better than the actual Campy manuals. As @ Andy_K says, it’s not trivial, but quite doable if you follow the instructions explicitly and don’t rush. Note in particular if you have a left-hand threaded pivot bolt!
