Hi there friend, if looking for a cheap but reliable keyboard consider this:
http://www.newegg.com/Product/Product.aspx?Item=N82E16823107120
That keyboard has very good reviews...
Edit: IF needing a USB Keyboard grab this
http://www.newegg.com/Product/Product.aspx?Item=N82E16823126097
Comes with the mouse as well, only for 17.99 and not breaking the bank.
OR even better
http://www.newegg.com/Product/Product.aspx?Item=N82E16823107006
It is technically just a keyboard but it comes with a free mouse as a gift. Only for 10.99
Edit 2: Just checked out the "gift" and the mouse isn't the best, in fact its a bit problematic but at 10.99 with a free mouse why not give it a try? Nothing to really lose, it is after all free...
