Keep in mind that there is Entry Level and then there is Entry Level.
I have no experience with the Canon lineup but I suspect it is similar to Nikon in that you truly do get what you pay for. If you get a bottom of the entry level grade camera body then you are going to run up against the limitations of that body very, very quickly. Low maximum shutter speed, relatively short shutter life, relatively poor higher ISO performance, having to dig through menu after menu to get to settings, and so forth. I never recommend anything on Nikon's lineup lower than the D5100 because I am of the opinion that the difference between the D5100 and anything lower is WELL worth the difference. You can either save and buy something decent now or you can start all over again in 6 months.
Personally my recommendation would be a used Nikon D90.
