best camer for beginner

[Raddy]

Purchase a 40/50d from KEH and a 28-135 lens from them.  Will save you money and purchase a great camera with a decent lens.

I had the 28-135 on my crop sensor 400D/60D but realized that it's not wide enough (though depending on what you would like to shoot of course). So I guess the previous mentioned EF-S 15-85mm would be a way better choice. It's wider and has a fair range.
On the other hand the EF-S 15-85mm couldn't be used on a FF body in case you wanna upgrade to FF at some time in the future.

without knowing your full budget
I suggest you buy a used body. 50d is great, but has no video.  They are cheap nowadays.
I 2nd the many suggestions of buying better lenses.  Buying a used body frees up budget for lenses, cards, flashes, bags, etc, etc, etc.  Did I mention that this is addictive?
Without knowing what your future plans are, I would suggest sticking with EF lenses in case you want to upgrade to full frame in the future.
Whatever you do, if you do consider buying an L lens ask yourself, "Can I afford this addiction?".  I don't know a single person, who stopped at ONE L lens.  I have 3 and going on 4.
