The Panasonic Lumix DMC-FZ28 may be what you are looking for. It has 18X Zoom - 35mm equivalent of 27 to 486 mm - and shoots Raw & Raw+JPEG. In addition, features all the user controls normally featured on a good dSLR. Currently available from various sellers at Amazon.com for less than $300.- (See link below for detailed specs.)

If you don't need so much reach or user control, your options increase dramatically, and the price drops as well.
