I have a Braun burr grinder, the kind you pour the beans in the top and the grounds come out the side into a container... appears they don't make it anymore... probably because mine is about fifteen years old and still going strong!
If I needed an espresso grinder I would look into the hand grinders, much less $$$
Edit to add, $300-$500 for a coffee grinder!?!
Sorry but hate the blade grinders... no way to get a consistent grind with them.
This is on my wish list:
