Only one I could find that is the form factor similar to the Samsung HMX-W200RN-C currently on sellout.woot is the Kodak PlayTouch Zi10. Mixed reviews on Amazon, but it is affordable, especially if you get one of the colored versions ($85 for black, $75 for orange or teal). It meets your desired recording resolutions of 1080 and 720(30/60).

This link should take you to an Amazon search result page for the camera.

This link is to a good video of a man using the Zi10 to record a test video with three different external mics.

This link is for a list of camcorders with mic inputs at B&H Photo Video, sorted with the lowest price first. B&H is a great company to buy from.
