I've owned a PLU ML-87 (Tenkeyless, Filco look-a-like) in White. The keyboard, aesthetically, appears to be exactly the same as the Filco. There are some major differences between the two, however. Overall, I think the PLU ML-87 is a great keyboard, but there are some things about it that may bother you.
At a high level, the board looks exactly like a Filco, but isn't at all. It's lighter and doesn't have that brushed aluminum casing feel. The spacebar, backspace and enter keys have a rattle to them (the stabilizers felt a bit off). But I think at the end of the day, most people were most upset about the 2KRO.
