The infamous "need help choosing a grinder" question, DF54 or... [$300]

Currently have a delonghi Specialista arte with a built in grinder, I was thinking it's time I upgrade my setup and maybe go with a DF54 from turin or miicoffee, I was also looking into a Eureka Manuele.

Is it worth it going for either of these or should I get something like a DF64 which would be a bit out of my budget. I almost always go with lighter roasts.
