WHAT ABOUT PRICE?

I,VE BEEN USING A LABTE CE0470 WIRELESS OPTICAL MOUSE FOR OVER FIVE YEARS, WITHOUT ANY PROBLEM, AND IT IS A $15.00 DLLS PRICED DEVICE. SIZE IS SO COMFORTABLE TAHT I USE IT TO DESIGN ARCHITECTURAL MODELS FOR ABOUT 10 OR 12 HOURS A DAY, WITHOUT ANY DISCOMFORT.IT DOES EXACTLY THE SAME THINGS YOU DESCRIBE IN YOUR ARTICLE.

I?D LIKE TO KNOW THE RETAIL PRICE OF THIS MS MARVEL.
THANKS
