Thank you all for your suggestions. My friend has been trying to suggest cameras, but she is busy with pre-holiday shoots and I don't want to take up too much of her time. I have a very tech-savvy friend who has been helping me also, and while I value his advice I though it would be helpful to get feedback from people who actually work behind the cameras.
chito beach, as for my bank: cheaper is always better as long as it is still a quality camera. Under $700 is a must but I would prefer something under $600 if possible.
Some models my two friends have suggested are:
Canon Rebel XS 10
Pentax K-X 16319
Samsung NX10 EV-NX10ZZBABUS
Nikon D40
Much simpler models than the ones that everyone here has been suggesting, but for a beginner who just wants to take action shots at shows for personal use, what do you think?
sensor performance and ISO performance I would suggest the Pentax K-X.
The K-X also will be ahead in overall cost savings as the body has the image stabilization rather than the lenses as Nikon and Canon rely upon, that makes the lenses cheaper for the same IQ and less weight also.
The Pentax is also weatherproofed the others are not.
With all the new beginner DSLR's out there I would steer away from buying used........the reason they are selling them is to get better quality than the one they are selling
