Currently got this one on my work laptop. Model M terminal board with internal converter. The only layout changes I made versus a normal 102-key are that RCtrl is is a Windows key, and the four keys along the right side of the numpad are =, -, +, and the normal Enter.

They use your standard Chinese cherry clone switches. Better than the rubber dome keyboards everyone gets by default, but nothing like a genuine model M. (the other reply linked to a model F which is likely better than the M but I wasn’t aware of that option until now so I’ll have to try it)
