Hey I am planning on taking my photography to a new level by investing in a digital SLR, but need some help making the right choices on gear! I have been looking at the Canon Rebel XTi or now the XSi. They seem to offer a good foundation at a reasonable price. I considered the 40D, but I think that is more than I am looking for. I also need to consider cost. However, the whole point of SLRs is interchangeable lenses, and I don't know where to start! I am budgeting $1000 towards 2 lenses and a tripod - is that reasonable? I would like an 'all-purpose' zoom with some kind of image stablization (preferably slightly wide angle) and a telephoto, reaching arround 200mm. I tend to photograph nature and landscapes, as well as a considerable amount of animal/equine photography. Any lens suggestions, or other comments? I'm new to this, so please take it easy on me Thanks!
