When buying a DSLR it is important that you buy into a system that will be around for many years so that you can be assured of the continuing availability of lenses, flashes and other accessories, as well as being able to upgrade the camera body when needed. The other issue is the quality of the said bodies, lenses, etc. Sony, in my opinion, fails to meet the quality and the longevity, that only Canon or Nikon can offer. Therefore, I would not recommend a Sony camera. It is a dead end.
There is no way that any point and shoot digital camera can equal the image quality of the cheapest Canon or Nikon DSLR. The Canon SL1 is a good purchase from the standpoint of it's smaller size and weight, price, features, image quality, reliability, performance, the fact that Canon will be around for many years and that all of the Canon lenses, flashes and other accessories will work with it.
