Cheap Slave Flashes for Canon Photoshot SX10 IS Camera

In Canon SX10 IS Manual they recommend 3 of their own flashs, Canon Speedlite 220EX, Canon Speedlite 430EX II and Canon Speedlite 580EX II. All these Canon Flashs are superb and work great. Only problem is their prices. all of them are above 100$ mark which might be too much for someone who look for less expensive things for their SX10 IS camera. After a quick research in Amazon I found few external flashes which are not so expensive. But all of them are slave flashes. Prices start from 20$ which is too low or a good flash but you can test thing at your own risk. I was told some had good result but who knows.
