AT101W and old Realforce boards are good suggestions. If Windows keys are a necessity, you're looking mostly at Cherry MX and domes, unfortunately.
I'll throw out one vote for a new production F77. Capacitive buckling spring, windows keys, a ridiculously thick/heavy zinc case, programmable, multiple vintage color options, etc.
I have been using one of those usb foot pedals mapped as a Windows key for AT keyboards myself.
