KB : Logitech K200
Mouse : Logitech M185(wireless but very good)
3 Yrs Warranty on Logitech.
Personal Experience (in Mumbai!): They usually replace it with new in a week if something goes wrong!
For Mouse Wired : Genius Netscroll 110X (it's a Taiwanese company,very good DPI!)
Or go for any Logitech Wired Mouse since replacement policy is good.
