Just when I was about to pull the trigger on a brand new XSI I came across a used 30D. It has been used as a back up body for a local wedding photographer and is in excellent condition. It has about 8000 clicks on it. I intend on using it with fast primes for concert (symphony/band) photography as well as in other low light situations where a flash would not be desired. What do you guys think? New "latest and greatest" or Used "proven technology"
