I totally agree with Eric. Alsp, something to consider, is what you might want to do in the future. At the moment, you only want a camera for taking photos of models, so the macro, and possibly 'super macro' features are needed. Image stabilisation is a good advantage, especially for the close-in, short depth of field you'll be using for models, as is the ability to control and set 'white balance'.
But, it may be that at some time in the future, you might want to take other pics - landscapes, portrait, sporting events etc, so it's worth looking at the next stage from a 'point and shoot' which could be worthwhile. These are sometimes know as 'bridge' camera', or 'hybrids', and are in between a full DSLR, and the compact 'point and shoot', and sre priced around about the same as the mid to higher range compacts, and a lot, lot less than a true DSLR.
I was trained as a professional photographer, and worked in 'the trade', for a major photographic manufacturer, finishing in the graphics photography market. Until a little under 2 years ago, I was still using traditional, professionl SLR cameras, but now have a 'bridge' digital camera, which fulfills about 95% of the tasks asked of the professional outfit I still have.
There are a number around, mine being a Fuji S1000 fd, the latest version of which is priced at around £150 in the UK, slightly less in the USA. This camera has a zoom lens covering the equivalent of 18mm to 400mm, with excellent optics, and a full range of features normally associated with an expensive, top range DSLR, and is a superb tool, conveniently placed between compact and DSLR.
