New Camera Recomendation

I’ve been using the Panasonic SDR-S26 for a few years now and I’m looking for a better camera to shoot yoyo videos. I would like an HD camera and my price range can be up to $500 if I find one that I think will be perfect. I only make videos every few months so keep in mind it won’t be something I use every day but I do care about the quality of the videos I make. Any suggestions you have would be great.
Thanks,
Donald
