Welcome to geekhack, Jippadox. Those are definitely some nice caps. I have too much money to spend on vintage keyboards with dead protocols and switch types to worry about such things though, myself. A satisfaction 75 would be nice though.
How are you liking the alt? I imagine that must be the smallest possible keyboard you can get and still reasonably navigate/highlight in spreadsheets with hotkeys, and whatever other arrow key-heavy tasks.
