I have been considering selling my Panasonic DVX 100A lately but I am not sure if this is a wise choice. First off, I purchased it 3 years ago and am not sure how much I should list it for. Secondly, I am not sure what a wise investment would be for a future camera. Some people have suggested the Canon 5D Mark II. Thoughts? I pretty much am at the stage where I usually rent higher-end HD cameras for shoots and have little usage of the Panasonic except for pitches.
