IBM model M keyboard

It is indeed one of the best keyboards ever manufactured. Unfortunately there just is no way to use it at work for me - quiet operation is required.

At Home: Sadly the UNICOMP-Keyboard is not 100% like the originals from the 80`s but I figured I find the extra (Windows-)Keys actually useful and there is a minor defect on my real Model-M that makes using the alt-key a pain.

The UNICOMP is the closest you can come to a real Model-M. I think it´s even better than some Model-M keyboards from the late 90s, but I might be wrong.

IBM made silent model-Ms - achieved very easily by packing the spring mech with grease!

Model-Ms are the greatest keyboards ever made.  I have had the one I am currently typing on for 13 years and it is frigging indestructible.

I love the Unicomp versions, plenty close to the original and worth every penny.  I bought the USB version for use at the office and I swear my typing improved.

Are the UNICOMP versions heavy?  Like, physically heavy, like an original Model-M?

This is an important factor.
