They're neat cameras. I would get one if I was planning on using it to travel and didn't want to lug around the dslr. I will say that I would highly prefer the dslr for advanced shooting. There will be quicker changes to the iso, f stop, and shutter that will be slower to adjust on the micros.

I know it's hard to find something in that price range, but don't exclude used cameras. I believe Canon and Nikon have a $500-600 model, which you can find used closer to your price range. If you are worried about quality/condition, go to a local camera shop. Most certify them after inspection.

I would try to stick to buying a Nikon or Canon. I have had bad experience with other brands. Good luck on the purchase.
