PowerShot A520
The price of a Canon powershot a520 depends from where it is bought. For example, on Amazon it costs $100; however, on eBay it costs $55. The price might be lower elsewhere.
The short answer is "yes." A few years ago I bought my wife a Canon PowerShot A520, a 4 mp camera with a 4x optical zoom. It still takes excellent photographs. The newer Canon powershots have optical image stabilization (IS) that minimizes camera shake. I believe IS is even more important than an upgrade from 4 mp to 8mp.
