The Logitech wirless keyboard is a good one for the money and no more RFI into the keyboard/computer.  

I don’t especially like typing on it, but it’s not bad.

Use #31 ferrite snap-ons.  I am not sure I would trust Homeland Security for electronics issues, security yes electronics no!

What is the manufacture and model of the keyboard?  My IBM keyboard finally bit the dust and I am in the market for a back light keyboard.  Would like to know what to avoid.
