I like my Baratza ESP grinder, but only because I also have the bellow attachment. Whatever you end up with don't forget the water spritzer to spray the beans before grinding. Also, you'll need a kitchen scale if you don't have one.
I think it would take me months to go through 3lbs of coffee as I only use one cup a day, which is only 11g of coffee.
I could have gone with a manual, since it's only one cup a day, but I know myself and would quickly be annoyed with the grinding process. Also, there is maybe twice a year I need to brew coffee when people come over. Does the grinder take space? Yes. It's like the size of a small blender. I put it in the dead corner of the counter top.
Let us know what you end up with. I may get a manual for travel fun.
