depends what you're looking for specifically, and budget.
any preference on KB switches? backlit? form factor? or are you just looking for something cheap with a lot of Macros. (a guide on some KBs, mostly mechanical. also comes with a link on recommended mechanical KBs : http://www.overclock.net/t/491752/mechanical-keyboard-guide)
what grip style do you use on your mouse? palm, claw or fingertip? are you into MMOs and need a multitude of buttons? or do you just want a simple 2/3 buttons layout? how big are your hands? how many monitors and what res are they? some of the most commonly recommended mouses are the Razer Deathadder 2013, Logitech G400/400s/500/500s, CM Storm Spawn/Recon, and the Zowie AM/FM. it's a real good idea to try the mice out in shops, holding it in your hands to get a good feel out of it.
