Need a new KB and mouse - recommendations?

[Cary]

My Logitech Cordless MX Duo mouse is experiencing intermittent double-clicks.

I called Logitech, and if I can find the receipt, and it's within 5 years, they will fix/replace the mouse.

If I can't, they will give me 50% off a new set on their web site: Logitech

They recommend the Cordless Desktop Wave.

Any thoughts? Insight? Should I look elsewhere? A different Logitech product?

TIA,

Cary
