I always go with blue for my microphones. They blow my mind with the awesome tech they come up with. They may not be cheap but its worth the money. Like £80 for a proper studio level mic. You can get some cameras for like £100 that are a nice, clear 1080p if you look hard enough. Also a lot of people don't think about lighting. get yourself a little headlight. I had one places behind my computer desk like so to turn on if lighting is not good on my face.
