My big beef with the repro types are that they spew the grounds all over the counter. I don't know what causes this, but I've seen this same complaint from others on line. I like their look, heft, and ease of adjustment for different grinds, but they have to work properly or why own one.
Several years ago Nate advised me that the '60s/'70s KA burr grinders didn't spew. I found one on ebay and it's been grinding for me ever since, no spewing -- it drops the grounds into the catcher just as it should. The hopper is smoked plastic and not removable, and the grind adjustment is on the bottom of the machine, but unlike the spewing, those issues are manageable.
