I think HP & Logitech are quite good. I've been using them for a long time and haven't had any problems with them.
I used to have logitech multimedia keyboard but after trying the TVS Gold keyboard, I stuck with it. (of course, there was no gum on the keyboard to stick to my fingers )
Microsoft Multi Media Keyboard Microsoft adds extra shortcuts and commands to the function keys. The F LOCK key lets you toggle between shortcut and function modes. I'm impressed by Microsoft's choice in shortcuts. You can shut down an application by pressing the CLOSE key instead of hunting for the X with your mouse pointer. You can hold CTRL and press keys on the QWERTY keypad to use other shortcuts.There is the SPELL key which shortcuts to the spell checker. Microsoft Wireless Optical Desktop and Logitech G11 Gaming Keyboards are the best. Features of Microsoft Wireless Optical Desktop There shortcut buttons on the left and right sides of the board .Each for My Document folder, the My Pictures folder, and the My Music folder. Other buttons start your email software, your Internet browser, and your IM (instant message) client. The middle group of buttons lets you control your media player application's functions, including Play, Stop, and Volume functions. I like the five numbered shortcut buttons on the left side of the board. You can easily assign each button to a folder, program, or Web site (just press and hold the button while your browser displays the Web site), and you can take a quick glance at your current shortcuts by pressing the nearby Show Favorites button.Logitech G11 Gaming Keyboard In addition to the standard 104 keys, Logitech gives you 18 extra G keys, along with three profile-switcher buttons that you toggle between three different custom G-key layouts. To match the Logitech G11 Gaming Keyboard there is SteelSeries Special-Edition World of Warcraft Mouse.
best keyboard is DELL/LOGITECH gaming keyboard XPS12 LIMITED EDITION sold last year more than 5 units for 260$ each
I use a Logitech G15 Keyboard. It's really good! Has 18 programmable buttons on it. Aswell as an LCD screen. And you can get a ton of plugins for the LCD for it.
