For a keyboard I would recommend something with Mechanical Keys. They feel much better and more responsive when you are typing and gaming. Unfortunately logitech doesn't make mechanical keyboards so you can't get one with a LCD screen. I think the LCD screen logitech puts on their keyboards are useless anyway.
Heres a really good post about Mechanical Keyboards. I recommend something with Cherry Blue or Blacks. http://www.overclock.net/keyboards/491752-mechanical-keyboard-guide.html
Also check out the Razer Black Widow. It uses Cherry Blue keys.
