I think it may be time to get a Dremel. I really have no use for it except for brush restorations. The Dremel 750-02 Minimite 4.8-Volt Two-Speed Cordless Rotary Tool, is priced right, but does it have sufficient power and battery life? I would appreciate hearing from our experienced restorers and whether or not they would recommend this model or a different one. All thoughts welcomed and appreciated.
