Suggest me a good Digital camera to buy?

I'm planning to buy a digital cam.
my budget is around 200$. 9000 INR.
Preferred make - Cannon & Nikon.

I have chosen three models

Canon IXUS 220 HS Point & Shoot(12.1 Megapixel, Optical Zoom: 4x, CMOS Image Sensor, with 2.7 inch LCD, 10665 INR)
Canon IXUS 115 HS Point & Shoot(12.1 Megapixel, Optical Zoom: 4x, CMOS Image Sensor, with 3.0 inch LCD, 9210 INR)
Canon A 3300 Point & Shoot(16 Megapixel, Optical Zoom: 5x, CCD Image Sensor, with 3.0 inch LCD, 8725 INR)
becoz all these models comes under my budget.

The third model which i have mentioned has most of the options but its still less in price, Why?

Also suggest me any good models which are cheap and best.

All i need is when i shoot a image or video and transfer to PC it should be in good quality. I don't mind the image quality in 3.0 inch LCD in the camera.

Why is Canon A330 less expensive?
- Shoots lower definition video (720 vs 1081)
- Does not have HDMI
- Slower maximum shutter speed
- Slower continuous drive (.8 fps vs. 3.4 fps)
- Lower ISO range (1600 vs. 3200)
- larger
