Why can't I get a camera that works??

Oh the frustration!  About a month ago I posted that the viewfinder in my Canon Xsi was not working properly.  I sent it in for repair and opted to trade up to a refurbished T2i.  I received that camera exactly one week ago and was loving it.....until......that's right, boys and girls, today the viewfinder on the T2i started messing up.  There is a piece that is trying to break off inside the camera and it won't show the picture to be focused, although it is. 

I am not a very happy photographer!  I know you do take these chances with refurbs but still.  It does have a 90 day warranty so I'm trading it for another T2i.  I hopefully will have better luck with that one.  If not, I'm not sure what I'll do.  I wouldn't mind trying a Nikon except that all my lenses and my flash are Canon. 

I hope that this camera works better than the least two (or at least longer!)
