Canon Powershot is one of the leading brands This camera is fine according to me. 16MP is enough to click high quality pictures. It has 18X Optical zoom so you dont loose quality while zooming in upto 18 times. It doesnt lag while clicking the pictures. One thing which some people might consider a disadvantage is the battery. You need to remove the battery and put in battery charger. Once charged you can easily click 300-400 pics.
So in my opinion this camera is worth your money if you dont have high expectation within a budget.
