The Keysonic compact keyboard I am, even after I have now bought a second one for the other PC, very satisfied. It provides (for the price) an appealing processing, a (despite "rubber keys") reasonably stop and is not too noisy. I can only recommend if the space is limited to the desk and / or you just do not want to have such a Riesentrum.
By comparison, I used the compact keyboard from Cherry. At double the price the keys were significantly more accurate, but also much louder and some keys like F11 / F12 could only be reached with as toggle. Also a good keyboard but the Keysonic like now better.
