Sorry for necroing the thread but I just bought the Deathstalker to replace my Lycosa and it's the best keyboard I used in a while. The chiclets keys, the weight, everything screams quality.
I bought the basic edition without the screen/touchpad and couldn't be happier.
I bought the Logitech G510s a couple months ago but sold it to a friend. Too much macro and other keys I never use.
