Are there any good and reasonably priced schools in New Delhi?

We might move from London to New Delhi in September. We have 2 kids aged 9 and 6. I have been searching in the British School of Delhi and apart from the price it seems quite difficult to get a place there. I wonder if somebody have information of other International schools or private Indian schools and if you think it will be difficult, so far, to find a place. Thank you very much Carmen
