Well, simple and short
Keyboards, mkplus master keyboard, found no links of it, but is a full key regular sized keyboard, ultrasim and ultra quiet, in fact, after knowing a few gazzilions keyboards, I can say this one pwns and costs near nothing, I remember being around 20€, awesome for gaming and regular use.
Mices, regular laser microsoft one for regular use and an razer coppermine (old) laser for gaming (FPS'n'stuff)
Pretty much it, TRY the keyboard BEFORE buying them, don't go on the hype, good spots are stores with public displays so you can hammer it around a bit and feel it, good keyboards are not necessarily expensive, unless looking for a special feature.
Mices goes the same away, get the feeling in the hand, does it fit? a small mice on a big hand may be a pain in the wrist and vice versa.
Really trying the shizz makes a good buy, like gf's
