Hey, recently me and a few of my friends are getting into making YouTube videos, though our friend that was recording for us, sadly past away. He used the Canon EOS 550D Digital SLR Camera.
Now without him we need to buy ourselves a decent, durable camera in the lines of about 300-350 maybe even 400 at a push!
So I have been looking into Digital SLR cameras and was thinking about buying the Canon EOS 1100D Digital SLR Camera, though if i bought it, I would not be able to use it before hand, so i'd like to get other opinions before I go ahead and invest in it.

I have also been looking into a few other camera, here is a list of a few...
-Nikon D3100 Digital SLR Camera
-Canon EOS Rebel T2i
-Nikon D3200 Digital SLR Camera Body Only

Though obviously the problem about wanting the Canon EOS Rebel T2i is the pricing is out of our range and would take a while to get the money.

So if anybody knows of any camera, preferably DSLR, that have too recording and sound quality, and hopefully within our price range, then please do tell me. Also if you guys have any advice on what I am speaking about then please that would be nice also.
p.s. The audio quality does not have to be that great if the camera has an audio input port, as I would eventually like to invest in an external "boom" mic, I think they are called, Feel free to correct me if i'm wrong.

-Thanks before hand, I'll be checking replies over the course of this month, and would hopefully like to make the decision by the end of the month, ready to record again next month.

Again, thank you for reading, and please, any help would be appreciated, without our "tech guy" that role has been placed on me, and your help is greatly needed. :P
