There is now a good alternative to update your DSLR and make small movies in a great quality ...the Nikon D5000....I was really bluffed by the D300s, and wanted to see the result with a lower level...which is nice !
The fact is you have all the advantages of a DSLR ( so you can change lenses, ...you couldn't make it with a videocamera ) ...and have a serious nice Bokeh , really nice definition ...
