I find that's true in specialised subs, but not wider ones. Like, if you're looking for a good coffee grinder, r/coffee will only recommend the top-end stuff, but if you search in something r/AskReddit you get more 'approachable' results.
They are correct for coffee grinders though, it's almost pointless to cheap out of them, you negate all the benefits of grinding it yourself when you buy a subpar non-burr grinder that doesn't produce a consistent grain size.
Buying a blade grinder is like buying a hammer with a spongy face.
Buying a blade grinder is a waste of money, but burr grinders range from $50 to $500 and while there is a significant quality difference, it can be reasonable to buy one at the cheaper end.
You can do OK with a blade grinder. I used to have one from Target, and I would grind in two or three stages, stirring the grounds with my finger (!) in between to get more consistent grinds.
A blade grinder is fundamentally incapable of producing remotely uniform particle sizes unless you're willing to sift the result and discard a substantial portion of the coffee. Stale pre-ground coffee will usually give better results and is typically the same price as beans.
I disagree. The most common recommendation is the $150 Baratza Encore, which is about correct for price/performance on the low end. The manufacturer sells cheap replacement parts for it, which is a massive convenience. They also sell cheaper refurbished grinders occasionally. I've had mine for 5-6 years and expect it to last much longer. Better electric grinders start at hundreds of dollars more (in the U.S. market).
This just means your "one of them" I've used a $30 delonghi for 10+ years. Its fine, people consistently complement the coffee, only someone in the <1% of coffee drinkers needs a $150 grinder. Like most people are ok with brown water from a Keurig. Someone who wants a beginner recommendation absolutely doesn't need something that's $150.
