Just pick up a simple keyboard for $10-15 and you're set. Nothing fancy that requires drivers and nasty software running in the background and whatnot, that's just an extra potential death-trap for your PC.
I'm still using an old keyboard with the huge 5-din pin connectors. Had to get a 5 din pin converter for 'em! Otherwise its a waste for me to buy new keyboards They only end up with coffee or alcohol spilt on 'em!
My advice would be, to buy a Microsoft Keyboard, what ever model. Microsofts hardware is usually top notch! (Surprising I know...) As they say, you get what you pay for, look for one with features that suit you, at a price that your comfortable with, and most importantly can you use it comfortably?
I want one of those roll-up keyboards which light up ^.^ Would pawn with my laptop connected to my Cars DVD screen.
