I have always liked Logitech for their prices and products. My dad has a wireless kb and mouse from them. They are around 5 years old and still work as good as they did when he first bought them.
When I replace the KB and mouse I have now I will probably switch to Logitech. Right now I have a Microsoft wireless combo that I picked up on sale and have had no problems with except for the range on the KB and mouse is really bad. I can't go more then 5-10 feet before I lose connection.
Hopefully I will find a deal on a good one like you did soon. Maybe with state taxes I will invest in one, who knows.
