I've only heard good things about the Diamond grinders, and raves about the customer service.
As with any stone-based grinder, my guess is that it will take a fair amount of time--possibly an unreasonable amount of time, as Brad mentions, depending on your process and other requirements--to refine to a smooth texture. It's definitely do-able--I haven't found that most craft chocolate I've tried to be particularly gritty--but it does take time.
I believe the machines Brad mentions are some form of a universal (please correct me if I'm mistaken). I've had some excellent chocolate out of universals, too, and they're definitely an option to look at, as well.
