Hi Loretta and welcome to the forums
Bizzarely someone was here only yesterday asking almost the same question.
The only thing you're likely to struggle for is a comapct that does ISO 1,200.
For your money, I would consider looking at a Canon Powershot SX120 IS. It has a 36-360mm equivalent zoom and has a top ISO of 1,600 (but compacts aren't great at high ISOs so be warned - this one will be one of the best in your price range though). It doesn't use Li-Ion batteries though, it's AA's but that really shouldn't be an issue. AA's last a lot longer than they used to and if you use a set of 4 rechargeables then you've always got 2 in the camera and 2 spare.
The best deal we found on that camera was £163 including an 8GB SD card (
