That fancy espresso machine grinder combo I bought used now scares me
I dropped $850 on a prosumer setup from a guy in Austin last spring, and every shot tastes like burnt rubber no matter how I dial it in. The previous owner never replaced the burrs, and I just found out that's a $200 fix on top of the cleaning bill. Anyone else get burned buying a secondhand machine and wish they'd just gone new for the peace of mind?
Bought my first real grinder off Craigslist three years ago, a Mazzer that looked clean but smelled like a burnt attic. Turned out the previous owner ran it with old oily beans and never cleaned the chute, so every dose came out with dark flakes mixed in. I spent a weekend taking it apart with toothpicks and microfiber cloths, and it still had that ghost of an old roast for weeks. Ended up paying a local shop tech $80 just to deep clean it properly, then another $120 for new burrs a few months later. I feel your pain, that hidden cost always lands right after you think you saved a deal. You are not alone in this one.
