Wow, its been a while since I've been on here...
As a youtube vlogger/filmmaker/beginning freelance video producer, I know how expensive and time consuming video production can be. And if you're not too serious about it, I suggest getting a $200-300 camcorder that does HD.
The main question I want to ask is what kind of magic videos do you plan on shooting? Youtube videos? Live magic videos? A trick for the wire? The answer will change what you may want to buy, and if you plan on doing a one-time thing like making a video for the wire, I reccomend getting a friend who knows a lot about video production to help you, or rent an easy to use DSLR, like a Canon t2i/550D or a Canon 60D. (Most places around where I live charge about $60 a day). You may also want to get a microphone if you want to do this, if you're shooting live magic, its much better to have a lavalier mic on your shirt to keep things clean.
BUT, if you're looking to get more into videography, I reccommend buying a cheap dslr. Like others said, you'll need to get a basic understanding of ISO, aperature, shutter speed, etc. But those are things you'll need to know as a videographer anyways. They look great, don't cost too much, and are pretty easy to learn if you look up online tutorials and just play with the camera.
Send me a message if you have any further questions
