I have a Canon rebel K2 that loads similarly except it prewinds. You just load it like the video above except there is no rewind knob and you just put the film in and close the door... it prewinds the film electronically and is probably the easiest SLR I've ever used. I think they can be had for pretty cheap used on ebay, and I'm thinking that most of the rebel cameras have a similar loading system. (I'm not sure of this, though... most of my experience is with the AE1)
