Grinder Suggestions to Pair with Silva [$300]

I got a silva and a rocky off marketplace. The silva has a PID and has minimal use but the Rocky has been inconsistent. I was thinking about selling the Rocky and getting a new grinder. I was deciding between a df54 or a starseeker e55. I can spent a bit more money but would prefer not to. Do you have any other suggestions? The goal is to get a grinder that is not stupidly bad for the Silva lol.

Thanks!
