Good answer blueray and vStyler!
Logitech is the way to go BB.
I've been using Logitech's now obsolete Cordless MX Duo since 2003 and it's still functioning like the day I bought it.
The one consideration most people don't care about when buying a keyboard is a measurement called key stroke life (KSL).
You can purchase a wireless keyboard for a buck or two at the 99 cent store and it could measure 15,000 KSL, meaning you'd have to hit a key 15,000 times before it may wear out.
Most of the newer high-end boards are rated up to or beyond 75,000 KSL.
Logitech boards are feature rich, easy to customize buttons galore, Zero tilt ergonomics and transmits from anywhere in the house. The matching mouse comes either left or right handed and is also loaded with tons of easy features. The mouse also comes with a seperate charging cradle.
To preserve your board, I highly recommend either a Safe-T Skin or Viziflex seel for two reasons. You won't wear out any of the key's face which is caused by oils from the fingers and even if you accidently spill an entire cup of hot liquid on your board, it will not get wet. These flexible skins do not hamper your ability to type.
Keyboard skins costs around $15 and is worth the small price to protect your investment.
The best keyboard on earth is the one that feels good under your fingers BB.
My Cordless MX Duo cost me about $105 six years ago, never had an issue with it. So to me it's worth every penny.
Let us know what you decide, ok?
