Despite a few shortcommings, it's still the best grinder I could find for home use.

This was the only burr grinder I could find which was best suited for home use.
Negative Product Points
It would benefit from a weighted base so that it doesn't move when the porta-filter is pressed in to activate the grinder.
The dispenser tends to drop most of the grinds toward the back of the porta-filter, giving an uneven fill. I tip the porta filter down so that the coffee will slide toward the front, then lift up to level the porta filter as it begins to fill so that the remaining grinds will fill in toward the back.
This machine has support tabs which fit the lip of most standard porta filters (I have the standard Faema e61 brew group porta filter on my Isomac Millenium espresso machine. This porta filter fits perfectly.)
Most grinders seem to have the unground bean hopper above, then a second ground coffee hopper below, and a doser lever. This means that I'm grinding coffee into a second chamber where it will age and begin to go stale. That's not really a problem for commercial use, because the high-volume use of the grinder means that those grinds wont be around long enough to have a chance to go stale. But I don't like the second chamber & doser for home use.
Instead of a ground coffee chamber and doser, this grinder dispenses the grounds directly into the porta-filter. The black button (seen pictured on the front of the machine) is pressed and activates the motor as soon as the porta-filter is pushed in. This is a very good idea since there's no chance that coffee will be going stale. It seems to be the *only* machine I could find which works this way.
I'm very pleased with the quality of the grind (which is adjustable). It has an indexed grinder adjustment to allow for course or fine grind. Since I am fairly consistent about my bean selection, it doesn't seem to require much adjustment.
This is not an enormous grinder. It sits on the counter top next to the espresso machine and doesn't take too much space. It really is stainless stell, so it looks great. The bean hopper is clear plastic, with a plastic top which merely looks like stainless. This is the only "fake" part on the machine... everything else that looks like stainless, really is stainless.
It's small enough that I was actually willing to buy two -- one is always filled with regular coffee beans, the other with decaf (for those guests who don't prefer to drink caffienated coffee after dinner).
TMR Inc. has been very good to work with. Of all the retailers I contacted, they seemed to be the most friendly, most responsive, and most patient when it came to answering all of our numerous questions.
