Is the buckling spring keyboard worth the 140usd$=120€euros ?
That's for you to decide. Note that you can frequently get second hand Model M keyboards for less than that locally (at least here they tend to go for EUR 75-100), but then you have to hope it works (although we're talking Model M, they probably do), maybe fix some small things (stabilizers under the big switches seem the weak spot), need to clean off a few decades of grime and of course have no warranty.
Is the silent version QT101 (=Quiet Touch R/D) better than buckling spring or other rubberdome=membrane keyboards ?
Can't comment on the new one, but I use a model M 71G4644 at work and it depends...
The exterior is identical to the regular buckling spring versions, with the deep sculpted key caps you have to love. You can however instantly feel that the mechanism is different and is very spongy compared to buckling spring. I would choose buckling spring any day, but if that's not an option (my colleagues would kill me if I did, it would ruin their enjoyment of the classic rock we always have on 😉 ) and you have to go rubber dome, the 71G4644 is one of the best I know. I slightly prefer it to my Leopold Cherry MX brown silent tactile keyboard, but that's really comparing apples and oranges. The Leopold has a far better feel to the key mechanism, but the keycaps and geometry is so-so, which is the exact opposite of the 71G4644.
Now, if anyone could only find a way to mod Cherry MX brown switches into a Model M case.... 😉
