Google searches do return some interesting results [2]. Although a keyboard/receiver pair can claim to use encryption it may be poorly implemented [1]. Logitech seems to use a proper encryption scheme [2] but who knows if it has some flaw that makes it easy to break.

Also interesting is this[1] and this[2] where researchers were able to wirelessly sniff keystrokes from wired PS2, USB and laptop keyboards. These signals are definitely not encrypted. :) The second link has info and videos. If the OP went with a wireless keyboard with properly implemented encryption it could actually be more secure than a wired keyboard.
