I can certainly vouch for the Vario. It's incredibly neat (no stray grounds), quiet and acceptably fast. No clumping at all, negligible retained coffee, and the timer works great. Also, I've never seen a mound of coffee as fluffy as it produces. (My little-used Max-Hybrid will be looking for a new home soon.)
Yes, it has more plastic than I wish it did, but it's sturdy, and I think the plastic would only be an issue if it's abused.
What I also appreciate is the small footprint. It fits perfectly in my small coffee bar
