I have a keyboard with what I think are Ortek made alps clones, and they aren't bad clones. They have a punch through the table kind of feel to them, a good sound, but they are kind of cheap and inconsistent feeling.
Beyond those negatives though, they feel and sound great, but the negatives are pretty harsh.
However, by looking at the wiki, it appears that the alps in this board, if they are clones, would probably be complicated clones. They couldn't be that bad.
