I have a canon sd300 that i have had to repair twice. The first time it was under warranty. The second time it was just out of warranty but i called and pestered them and they agreed to to a one time courtesy repair for no charge. Within 3 weeks ive got the same problem again and they say that the i have to pay 100$ to repair it. Im wondering if its worth trying to repair this as its lasted 2 months after first repair and 3 weeks after the second repair or whether calling them and whining is going to get me results. If anyone has had a similar experience, Id appreciate the advice. Thanks.
