I use a model-f terminal keyboard with a small microcontroller to convert it to usb. It's pretty great. I used to use model-ms but they became hard to get, and I gave away far too many of them back at a time when they weren't scarce. (I still have two, but can't replace them at a reasonable price if they fail) The extra keys on the model-f terminal keyboards are handy too. There was a window where I worried that my two remaining model-ms were going to have to last me the rest of my life. Fortunately there are now a lot of mechanical keyboards available at reasonable prices. I like the model-m and model-f keyboards somewhat better, but many other mechanical keyboard choices are pretty good too.
