Yes!!! I say keep the Robur or yeah buy a newie, you just seem to love it, and while it may not be 'pretty', I think what you're getting out of the grinder far outweighs that. I never even consider what a grinder looks like really, as long as it works well! Of course to each their own, but yeah sounds like a rockin' grinder.
Good call Grant
If I say I have a bigger machine than you, it is true and it can be measured with a tape measure. A very short argument.
Many of the things with grinders especially are features which mean something good to one user and important and maybe the opposite to another.
Flavours can't be measured with a tape measure and so the arguments are endless (not a bad thing).
In the case of this machine I just like it. Some of that is the extreme robustness and indestructible nature of the beast. Some of it is obvious stuff like the quality of the grind which I can see even if I can't be 100% sure whether it means better flavour. I also like the idea of having an industry standard so custom burrs and all the parts will be easily available in 10 years time.
I like it and maybe whether you like a piece of equipment or not depends on factors that it is hard to put your finger on. My Wega Mini Nova Classic for example has a rotary pump. I won't ever have a machine which isn't plumbed in and doesn't have a rotary pump. I love the sound, the smooth power and that probably isn't too logical...maybe. I did have someone today though, an industry expert tell me just how superior rotary pumps are with very even pressures and no pulses but...
It may be one of the things I love about the Robur is the 900W motor and the way it quietly munches a shot in just a few seconds totally effortlessly and sounds almost bored doing it, no big deal.
Maybe that is it, the same way I have a 200kW Toyota Aurion rather than the boring 4 cyclinder...
