CompUSA.com offers the Logitech VX Revolution Cordless Laser Mouse for Notebooks, model no. 931690-0403, for $49.99. This $20 mail-in rebate cuts it to $29.99. With $3.75 for shipping, that's the lowest total price we could find by $6, although it was $10 less a month ago. This mouse's "Hyper-Fast" scrolling feature tries to figure out the best scrolling mode for the application you're using. Other features include a document "quick-flip," a button that searches your favorite search engine for the highlighted text, laser tracking, and more. Logitech.com has more specs. Rebate expires May 13.

Update: Amazon.com now charges $32.99 after its $20 rebate, with free shipping. That's a buck less than CompUSA.
