For keyboards, I'm quite fond of my Das Keyboard (blue switches), although I wish it didn't use glossy plastic. I also love my IBM Model M at work, although I don't game on it
. The Das is probably not the first choice for most people for a gaming keyboard, but I value the tactile feedback and sound more.
My favorite mouse so far is the Logitech MX518. I've since replaced it with a G500 as it started having issues, but I haven't quite warmed up to the G500. My biggest complaint is the cord, I dislike braided cords and it still hasn't straightened out (I flip the mouse over back and forth every couple of days to try to undo it). The MX518 still works for the most part (left mouse button is iffy), so I've kept it as a spare.
Thanks for posting the link to the G400 ironweasel
, I didn't know that it was around. Pretty funny that the box mentions the MX518.--
