ya, i agree that you shouldnt buy expensive ones if they are corded. but, you should not buy cheap wireless keyboards. i bought a wireless keyboard/ mouse combo from walmart for 30 dollars, and believe me, i got what i paid for. i have to change the batteries every 2 weeks, and sometimes there is lag between when i press the key and when it appears (i.e. i press a key and it shows up on the screen 2 seconds later) so ya i am back to a wired keyboard now.
