Best Wireless KB and Mouse

Any suggestions on a keyboard with the following features?

1) compact (not big, I'm using it on my laptop)
2) wireless (with good connection,) I have one wireless keyboard which is a peace of ***, it really lags and so.
3) not expensive
4) has customizable keys
5) has typing (not gaming) in mind.

And a wireless mouse with the following features:
1) wireless (with good connection)
2) not expensive
3) doesn't need to have 1000 buttons. A simple working one is enough.



I know this is the CPUs section, but there is no other place where this fits.
