Very popular in Germany.
The new BX series is also very expensive.
Though I think the K10 for ex. is a good engine, there just IS this mentality that engines have to be Italian, so I think RB having engines produced in Asia damaged their image a bit, right or wrong. I previously had written them off because they were so expensive, but then they came out with the Asian-built stuff, which was just more expensive than the Asian-branded same thing. Last year though they started selling affordable Italian engines like the Fire 11, which is why I got one. Seems kind of like all the Asian engines were their "New Coke", and now they're getting back to their roots or whatever..
(I've run with a few K series engines before though, and they were plenty good..)
