To battle all the "Rich" Comments:
About 10 years ago, I randomly came across a Craigslist ad for a "Commercial espresso machine from bakery - for sale" - No photos, but the way it was described I had a feeling I knew what it was. I contacted the guy, asked for some photos, after reviewing the photos, I realized it was a 2 Group LM Linea. I asked him what he wanted for it, and he just wanted $500 for it. I drove 6 hours, picked it up, brought it home. - At the time I was rocking a modified Silvia, and Rocky combo, that I got on CL a year earlier for $700.
I spent the entire summer taking the LM down to its frame, citric acid bath, cleaning, refurbishing every part, replacing things as necessary, and upgrading. After about 6 months, and another $800 in parts, I had a fully working 2 group LM linea in impressive condition. I listed it for sale on CL, and ended up selling it at the time for $4k. I then in 2010 made a few phone calls, and scored a fresh off the boat GS3 with a decent discount for a little more than what I sold the Linea for.
Over the years I've purchased, refurbished, and sold a lot of grinders as well. I found a local cafe selling a Mythos for cheap, because it needed work, Spent $600 on it, maybe another $300 over the course of a few months on burrs, and customiziation, and I'm now sporting a LM GS3 MP (fairly modified, but I'm not including that in the costs because I've done a lot of that myself), and an older but still really good Mythos, (also fairly modified) for maybe... $2500 out of my own pocket.
Yes, I tell people my coffee set up is worth more than any car Ive ever owned, but, I (and possibly others here) have worked for what we have, in one way or another, not that we are rich, or maybe we are, we just find our ways to enjoy our habits/hobbies.
