Wacom’s top-of-the-line pro model works with both pen and fingers, so you can alternate between using the pen and multi-finger touch gestures. Available in small, medium, and large sizes, its 2,048 levels of pressure sensitivity make it practically essential for fine retouching. You can configure ExpressKeys to minimize use of your computer keyboard for retouching, and a $39 kit will convert it to wireless.

$210 to $434, street, according to size.
