boonerboy,
I am a Canon Camera user. I love them! I own a Canon 30D and a Canon 40D. I have often thought about upgrading to a 50D, but I really would only be gaining a few mega pixels, so it really isn't worth it to me.
I have posted the following specs below, go ahead and read them and then towards the end of the post I will give you my thoughts:
Canon Rebel T2i specs:
# 18.0-megapixel CMOS sensor
Creates an effect 1.6x field of view and captures high-resolution images up to 5184 x 3456 for images with exceptional clarity and tonal range.
# EF-S 18-55mm f/3.5-5.6 image-stabilized zoom lens
Included for intricate picture detail. EF lens mount for use with Canon EF and EF-S interchangeable lenses (other lenses not included).
# 3" Clear View TFT-LCD monitor
Features Live View technology, 160° viewing angle, approximately 100% coverage, and an antireflective and water-repellant coating for a clear and smudge-resistant surface. 7 levels of brightness adjustment.

Isolates subjects in-frame and optimizes conditions to take the best pictures of friends and family.
# 63-zone TTL full-aperture metering exposure controls
With auto, manual, program, shutter- and aperture-priority, depth-of-field EA and E-TTL II auto flash modes.
# 9-point autofocus
With auto, one-shot AF, predictive AI servo AF, AI focus AF and manual focusing options.

With E-TTL II auto flash metering and flash-ready icon lights visible in the viewfinder.
# White balance options
Include auto, daylight, shade, cloudy, tungsten light, white fluorescent light, flash and custom. White balance correction and white balance bracketing for natural tones in different lighting conditions.
# Full HD movie mode
Captures video at selectable resolutions, including 1920 x 1080 (at 24, 25 or 30 fps), 1280 x 720 or standard-definition video a 640 x 480). Movie crop function for cropping a standard-definition movie up to 7x magnification.

Both cameras are Awesome! I think the T2i due to the more mega pixels and the lower price would be a great choice for you. That way you can get the two Kit lenses instead of just one lens.
As far as I am concerned, I would be looking for just a camera body only (no lenses with it) and then with the money I saved I would be buying Fantastic lenses that are Professional Quality and have an L on them! The lens is what brings the picture to the camera to make a Photograph!
I have just recently purchased my third L series lens, a 17-40L to compliment my 70-200 L telephoto and my 400L telephoto.

If you are interested, I have a great little 24-70 walk-about lens that I am going to be putting up for sale at a reasonable price. Drop me a pm.
Good Luck on choosing the perfect camera for your needs!
