Welcome to Geekhack!
Sorry to hear that you tried to buy something from berserkfan. There's a lot of us in that position. I was tempted to buy one of his F122 keyboards, but in the end settled for just a keycap set. I ended up getting an old numpad that no-one wants. The keycap set is still MIA
I do have one Model M 122, but it is currently not working. Well, it probably works, but has no keycaps and no adaptor, so I can't test it. It is on my list of things to do.
During the meanwhile I am alternating between my two SSKs and occasionally pressing one of my Model M 101 key keyboards into use.
I like buckling springs
