I'm looking for a camera or camcorder that can provide high speed video in HD.

I have used Casio's, which can record at 120 fps (which is fast enough), but the video quality is not very good.

There are specialty video cameras that can do high speed HD, but they cost over $100,000.

I thought that a compromise might be a camcorder or camera that can record 60p in HD. Could this be edited at 30 fps to reduce apparent speed by half?

Or, are there any prosumer HD camcorders or cameras that can record 120 fps.

I also need to be able to set the shutter to 1/1000th of a second.

Any suggestions appreciated.
