700$ is too expensive to me, 200$ for a good enough camera is a good price.
The guys recommending a Canon SLR are not serious (I hope) You seem like you need something that is fully automatic and easy to use. An SLR based rig is not that.
ANY of the entry level camera camcorders will produce outstanding video images if (big IF, so do this) If you have enough light, lots of light AND you place them on a tripod. So you get your $250 or $300 camcorder and some big lights and a tripod.
Next comes sound. It is REALLY hard to gt good sound, harder than getting good video. the rules are (1) place the microphone closer to the subject. (2) find a way to get it even closer, use a lavaliere microphone or a boom mic. (3) NEVER use the camera mic. EXCEPT for synchronizing an externally recorded sound track in post. (4) after doing the above, upgrade the Microphone, good ones start at well over $100,
As an example, I can get good interview footage with 1000 Watts of light, a $250 camcorder and a $400 Tram TR50 microphone. My Rode N1a mic is outstanding for void over recording and glands eel with the tiny Tram mic.
Where the Cheap $250 cam corder falls down is if you take it ti places with poor lighting, that is either to dim or uncontrolled, light bright noon sun on a clear day. the low-end camcorders need you to think always about the light.
Things to look for #1. A microphone jack. No jack is a 100% deal breaker. Althought I have recorded without it, I use a portable audio recorded to record sound then attach it to the video later editing. But most of my shots will have voice over that is recored days later after the video is shot. I do instructional stuff.
Next feature is a good "OPTICAL" image stabilizer for those times when you must shoot hand held.
Best camera that has all this at the best price is the Canon - VIXIA HF R400 HD Flash Memory Camcorder. It is on sale right now for $200. just get it and be done with it.
Or really if yu are serious about film, buy two. It make editing easier if you shoot with multiple cameras.
