I've processed one of your photos to make the bands more obvious. It's much less noticeable in daylight shots, but that doesn't mean it's not there. It's usually hiding in the shadows. In fact, look at the satellite dish in the original photo more closely: looks familiar?
Is it time to buy a new cam or go for repairing? If is time to buy a new cam, should i start with a prosumer or dSLR? If want to repair, which shop to go?

By the way, thank you , cjtune. Thanks for helping me to get answers for my question.

Most probably not worth repairing but why not ask to see how much it'll cost you?

No matter what type or model of camera you're buying, please test it out before buying by doing a number of high ISO shots underexposed or in a dark setting. If you candidate camera can have it's EV adjusted (either has shutter or aperture priority mode, or fully manual mode) to about -1, -2 EV and see if you can spot any bands.

Both of my S$2000 E-330 and S$1350 E-510 has bands at high ISO too and I am disappointed with Olympus for this. But at least there are a lot more other features in them to enjoy.

How high is the ISO that can let bands to occur?

My compact has a highest ISO at 400 and you know, bands occur.

It varies from camera to camera.

Nikon's DSLR dont have much banding or in fact none at high ISo up to 3200. It may have a lot of noise though.

Depends also from batch to batch.
Some are faulty batches, like early Nikon D200, and some Canon 20D, 30D.

Those that I know that bands due to design limitations are the Pentax K10D and any Olympus DSLR that uses the NMOS sensor.
