It's on the high side of your price range, but my Panasonic DMC-FZ5 has been great. I'm not camera savvy and don't have a great command of photography and am still able to get very good pics with the most basic settings (what I consider good pics). I'm sure with a little studying, my pictures will improve a lot. It's easy to operate. Any of my pictures on this forum, within the last 6-8 months, have been with this camera.
Also, most of pics in the link in my sig. area are with this camera.
I hesitated at the cost, but seeing as how I went 20 years without a camera at all, this one will last me quite some time. Plus, there are great websites (butterflyphoto for example) where you can find top notch cameras for much less than at big stores like Best Buy (they are usually new in-box/not refurbished, but you should always check before buying).
