Why the need for an uber costly grinder when many inexpensive blade grinders can grind as fine as you would want?

Better consistency of the grind. And there are many medium cost burr grinders (around $50-75) that will do adequate for the majority of users.

I have a Mr. Coffee grinder Rob which works just fine for me. I set it at the "fine" setting and "12 cup" setting, place 4 tablespoons of coffee beans in and let it rip through its cycle. This generally powders the beans with good consistency. I then place the grounds into my Melita one cup with a #2 brown filter, and we have a great cup of mud:-)

It's easier to get a more consistent coarser grind with a burr grinder. Just get a manual burr grinder if you're on a budget.

I have the same grinder as MarkinCA. I use mine for a coarse grind mainly for my FP. For about $20-30 its gotten the job done pretty good for three or four years.
A burr grinder will give you a more consistent grind if you need/want one.
