aqsg72 said:I'd personally get a Microsoft one, something like the Wireless Optical Desktop Elite http://www.microsoft.com/hardware/mouseandkeyboard/productdetails.aspx?pid=016
Thats my personal recommendation from Microsoft keyboard/mouse combos.
The best Logitech for $80 would be the Cordless Desktop LX 500 http://www.logitech.com/index.cfm/products/details/US/EN,CRID=486,CONTENTID=8773
Of the two I'd go for the Microsoft one
