Wireless Keyboard w/o a Wireless Mouse?

Pampusik asks: "I'm looking for a decent wireless keyboard, but do not need a wireless mouse. Unfortunately, it seems it is nearly impossible to buy a wireless keyboard without having a mouse bundled with it. The only wireless, mouse-less keyboard I've been able to find is an option from Logitech. It is, however, not an impressive keyboard. Are there other options available?"
