I am interested in video production and filming (although I have very little experience), and I thought that Youtube could be a good way to learn how to do it a bit. I have all of the audio and lighting worked out, I just need to figure out the camera. I want to keep the camera around $200 including a tripod and SD card. I was wondering what would be the best option is. Also, should I get a 1080p camcorder, or is 720p good enough? I looked at the Sony Handycam with accessories for about $240, but that is a bit out of my budget. I also looked at the Samsung F90, but it is only 720p and I am not sure if that is likely to be a problem. Like I said, I am inexperienced with this stuff. An external mic port is a bonus, but all my mics are XLR, so they probably would not work.
USAFRet is right. You can find some good used equipment at B&H Photo & Video (be sure to shop the Used Dept.). Though some do record in full HD I didn't find any with a microphone jack in that price range. The key is to find something you are comfortable learning with and get a lot of practice shooting and editing. As has already been mentioned the most important piece of equipment is the person behind the camera.
One difference being that no budget is posted in the other thread. If this is indeed a duplicate thread then I suggest you keep one and close the other as you have a better chance of getting help with just one thread.
