many thanks for fine advice

what would the group think about cleaning the Mazzer mini vis the MACAP M4, especially the dosing chamber?

thanks again!

This grinder review summarizes how they compare. If you allow for modifications (e.g., Improving Mazzer doser efficiency and How to Tame a Messy Mazzer Doser), neither the Macap M4 nor Mazzer Mini hold an advantage over the other in terms of neatness.

While I can't speak from experience with the Rocky, I've owned the Mini and both a used and new Super Jolly, and I've reviewed the Baratza Vario along with Dan and Jim. I wholeheartedly agree with his assessment in placing the Vario close to a Super Jolly (and above the Mini/Rocky)--Depending on one's priorities, preference could go to the Super Jolly or the Vario. The Vario is a dream grinder for someone looking to minimize retention and keep the insides of their grinder clean. The Super Jolly has a definite edge in that it's a little less 'finicky' and obviously way, way better built. I'd also say it's easier to keep your counter clean with the Super Jolly (with a few doser mods): the Vario occasionally has static issues that will leave some grinds in your work area after dosing.

If I were in your situation, I'd strike the Mini, M4, and Rocky off my list and try to decide between these two.
