Is SLR worth the extra cost on a digital camera?
Having problems with my old digital camera and I will be replacing it. I’d like to upgrade…I am not a pro, but I’d like to get better quailty pics as I will be travelling alot in the next 2 years …what do you think? Should I just invest the extra dollars? Also , are the lower ends okay..I really don’t want to invest 1k into a camera. What about this one if I go SLR…?
Canon Digital Rebel XTi 10.1-Megapixel Digital SLR Camera & 18-55mm Lens – Black
Thanks very much; any advice / tips on buying is greatly appreciated. I am of course checking out ratings for cameras , but it would be nice to have a little more than that to go on. 
In your case absolutely not. For that money you’d be much better off with a high end point and shoot such as a Canon G series. These cameras have near SLR functionality and their image quality is great.
The reason I’m saying this is that the 18-55mm lens is a “kit lens”. It’s designed specifically to be thrown in with a camera at little cost to Canon. It’s build quality is cheap, it’s optical quality is poor, and it actually ends up being a 29mm-88mm due to crop factor, which is not particularly impressive compared to a high end point and shoot.
If you want to buy an SLR be prepared to spend a few thousand dollars on good quality zoom lenses in the focal lengths you plan to use, or buy fixed focal (no zoom) length lenses that will still run you hundreds of dollars each.
