Amazon has the Black & Decker RTX-B 3-Speed RTX Rotary Tool Kit for $22 with free shipping on $25+. Normally $30 to $40. 3-speed tool features a flip-lock spindle lock mechanism and a universal collet that accepts all standard rotary tool accessories.
Got one of these in a previous deal... excellent device, and it uses Dremel bits.
It was $30 a week ago. Probably going to snag one!
