Chiming in to provide another anecdotal experience. At a drip grind size on my 1zpresso JX, I take no longer than half a minute to grind an 18g dose of beans and it requires nearly no effort at all. If you're trying to keep the budget under or around $200USD, the brews you get from a nice manual grinder are significantly better than what you can get from an electric grinder at a similar price point, but you are trading convenience. If you're entertaining or brewing for more than a few people regularly though, it might be worth the tradeoff. For me, the flexibility and portability of a manual grinder were definitely a priority, since it allowed me to take a very compact brew setup while traveling so that I wouldn't be stuck with bad coffee while backpacking/in hotels.

Yes, they are. I pre-measure the amount in the evening and in the morning, while the kettle is getting hot, I grind it and put it into a Phin (vietnamese coffee filter, you'd be surprised how good it is) well before the water's ready. While it takes its time to drip I cook up something quick to eat... and that's been my morning for the last few years :D

Good manual grinders are definitely easy and fast enough for daily use, with the caveat that it's going to depend on which type of coffee you are brewing. Pourovers/french press? Easily. Espresso? Probably a bit harder, and will require a better grinder.
