And that's exactly what I did. So, based on feedback from others, I bought a Yakamoz router bit. True, I haven't used it yet, but I put it on the router, it doesn't cause vibration even at maximum speed, which means the bit is balanced. The cutting edges are smooth, a set of spare ball bearings is welcome. The price is very affordable even with shipping (I don't live in the US so I have to pay for shipping) so overall good value for money.
