Coffee

There are a few things to note: burr vs blade. You do not want a blade, because as others have said, the key to the grind is consistency of granules. Coffee ground too fine tends to over-extract, be bitter, and even clog equipment. Coffee ground too coarsely will under-extract, taste kinda earthy & "bleh", and it's a waste of bean.

The two best electric burr models on the budget side of things, AFAIK, is the the Capresso Infinity & the Baratza Encore.

The Capresso Infinity is the cheapest quality burr grinder you can get; it is gentle & slow grinding. Very consistent. Unit size is small, which is nice.

The Baratza Encore is SUCH a capable grinder. Very well known. It's got a nice "heft" to it, so it stays put while grinding. I had a very oily bean that I sent through the Encore, so much that it choked & stopped up. I carefully cleaned it all out & it works just fine. What a champion!! Unlike the Capresso Infinity, it can crank out a more than acceptable espresso-level fine grind.

Between capability & reliability, the Baratza Encore wins my endorsement. If you don't care about espresso & you just want a good machine without spending all the money, then & only then would I recommend Capresso Infinity.
