i'd recommend one, but i've not ever played with a mahlkonig or a robur or anything, so it's hard to compare. certainly smokes a super jolly, though. grinds an 18g double really quickly, and on my gb/5 the espresso's texture comes through syrupy and smooth. i like tools that give me no excuse if the drink sucks - if it's bad, it must be barista error. the k-10 does that so far.
