The canon 30D is a great camera and it's about 1400. CAD with the crappy lens and memory card if you shop around.
The XTi is also a great camera and it's cheaper - it's a bit less solid than the 30D but that doesn't matter to most people.
If you want to get more serious about photography (that is to say maybe trying photography as a hobby or learning about photography) STAY AWAY from cameras that you cannot change lenses with or have no manual focus option. JMO
