Newegg offers the Logitech G700s Rechargeable Wireless Gaming Mouse, model no. 910-003584, for $44.99 with free shipping. (Amazon charges the same.) That's the lowest total price we could find by $15, although we saw it for $15 less in July. It features 13 programmable controls, storage of up to five profiles, USB recharging/data cable, and 200 - 8,200 dpi resolution.
