I can help you with this. I'm in charge of a technical department at our college and we have a ton of Canon's. The students are sometimes a little hard on them and we do get many repaired. Most shops you'll go to will either fix the lens in the camera or they install the cheaper aftermarket lens or used parts. We have a company that all of our Powershot's go to. They specialize in these Canon's and that is all they do. They have a service package where you get the whole camera completely serviced and it includes the brand new original canon lens installed as well. Our cameras come back better than new every time. You get a brand new lens, the whole camera gets serviced and properly adjusted, their service is totally amazing. I have a coupon that you can use as well. I'm not sure when it will expire but as of right now it still works and it gives you an Instant $10.00 Savings making an amazing deal even better. Here's the link to get it looked after, the coupon can get used at checkout. During checkout it will ask for a promo code, just enter: save10now
The link for the service package is as follows:

Good luck with it, that site is the absolute best for a Powershot.
