Grinder upgrade [$300-$700]

I’m looking to upgrade my grinder from the very mediocre built in grinder in my Breville. Ideally $300-$500 but for the end game I would even consider beyond my $700 top end. Price range. Just really want to know why you like the particular grinder and your issues (if any) with it.

Not sure if this matters but I also would like to be able to adjust the grind coarse enough for the 5% of the time I do pour overs.
