I used to be a big fan of doserless grinders. They certainly have appeal to someone who keeps on reading about using freshly ground coffee all the time. What I found, in practice, though, is that they tend to have a few drawbacks. Clumping and heaps of mess are big ones. Most doserless designs seem to be the equivalent of a doser design and, therefore, still have an exit chute from the burrs that holds up a few grams. I hope that people realise this and purge it clean, just as they would on a dosered grinder. Then let's not forget the "stand there for half a minute holding the pf" thing.
I ditched my doserless rocky for a dosered mazzer mini and couldn't be happier. The standard doserless designs don't appeal to me much. The mini-E gets some bad press, but I set one up to demo one of our machines the other week and I have to say that I wouldn't mind one. I was actually able to adjust it to grind the perfect amount for a double shot with one push of the button! After we had made about seven shots there were maybe twenty grains of coffee on the table. What more do you want?

It just make more sense to me, instead of goin' crazy on the doser "swept" lever like crazy, don't you think?
Plus cleaning the thing every other time...
What decent commercial doserless grinders are there?
We tried the Mahlkoenig out and it was great for a while, but a bit of a PITA. The stepped adjustment really threw the timer out of whack and it dosed MASSIVE clumps. Plus the exit path seemed to be really long ... hate to think how many stale grounds sat in it. Some people think that they grind so fast that they burn the coffee. Mahlkoenig now have a stepless version, which might be an improvement. The grinder does have good aspects, though; the PF holder is really good, it is relatively low on mess and wasteage and it grinds relatively quickly.
The Brasilia competition grinder is a bit ecclectic ... haven't even really heard of anyone else who has one. If it weren't for the incredible amount of mess that it sprays everywhere, it might be the perfect doserless grinder!
I have to say, though, that I'm surprised that more places aren't modding their mazzers. The toilet roll in the centre thing actually works surprisingly well, and it allows you to remove the dosing chamber plate so that you can halve the number of pulls required!
