If you truly want to value Sound/Video you have to get into the Prosumer/Professional range of video cameras. Those are going to set you back from $1200 (Canon XA11 or an older XA10) and up which it sounds like is more than you want to spend? We just bought a new XA15 because our old camera gave out. It was about $1700 for that one all told, but hopefully we'll get at least another 8 years out of it.
Like Techy said though, if you don't want to spend that much just use your phone and get a tripod mount and an external mic.
