Firstly SD is dead for anything like your projects, the quality of HDV is far better if you're going to transfer to film. Secondly the Canon will do 25p (for PAL don't do 24p) and the latest Canon is seven years on in technology terms.
Ignore those who think all compression is bad and therefore HDV can't be up to much. The millions which the manufacturers have spent developing (and updating) HDV has resulted in an ideal format for those who want to enter film festivals etc.
