Im just a newbie to this forum but have found the advice herein a tremendous help. I have leant that the more you can spend on a grinder the better your coffee will be. (You also need good beans too) I had originally decided to spend around the $500-600 mark but have just spent $250 on a great secondhand grinder. (Fiorenzato t80) It has given me a top quality machine that will provide a top quality ground bean, without the higher cost.
If you keep an eye out in this forum there are occasionally grinders for sale otherwise keep an eye out in your paper/trading post and you may get one local. But make sure you get some advice before buying especially from CS members as they have a great wealth of information.
I cant offer any advice for a grinder sub $200 sorry. I am not sure what to recommend. But good luck.
