I recently obtained my Sigma AFK-7100MC which uses White Alps for all the keys except the enter key which uses a Black Alps switch.
I do not know what they are exactly (ie. fake or real) but they are clicky, tactile, loud and genrally feel lighter than my rubber dome.
Oh, and the weight of the keyboard is quite heavy, heavier than a cr4ppy $5 rubber dome but lighter than my tank of rubber domes, a HP Multimedia keyboard from back in the days of the beige.
My HP rubber dome I currently prefer![](http://i3.ebayimg.com/03/i/000/d9/9a/8edb_1.JPG?set_id=7)
The Sigma is very dark beige and is also smaller as it gets rid of the cursor keys and the set of INSERT DELETE HOME END etc. keys between the numpad and the qwerty layout.
My Sigma AFK-7100MC...was it called AFK because it feels so bad and no-one uses it? lol![](http://st.cat-v.ne.jp/pgr/keyboard/jpegdata/mackey.jpg)
So, I am feeling kinda left out...I right now at this moment of time prefer the rubber dome HP keyboard but is this normal?
I also feel that the rebound speed on the rubber keyboard is much faster than on the Sigma, affecting my typing fluidity. Maybe it's because I'm bottoming out, not used to the lower throw?
Oh, and by the way, the Sigma has quite a low throw and so the keys look significantly shorter (ie. like modern day cr4ppy OEM rubber dome keyboards)
