>>7210243>what do you think about the harder and steenbeck infinity CR plus 0.2mmI've never used one so I can't say much. Looking at the schematics it seems to be more mechanically complex than PS770, the cup is smaller and it has no MAC valve, other than that it looks like a well made brush. I'm sure there are people who swear by it.
I think it all comes down to parts availability and price where you live. At the very least you should be able to get a spare needle for it.
