Tommy - while fun, if you're going to take product shots you need to master multiple strobes. You're post processing your stuff and the edges are looking weird as hell in some shots. If you're going to do a white background on a part with a lot of edges you need a smaller aperature so that the gap between a fin and its background aren't a blurry mess. I do product photos for the company I work at and have a great setup using my Canon 50D w/ 580EX II flash and 2 430EX flashes as remote strobes. You will find that you are not photoshopping nearly as much and it looks more natural. Stop the lens down to like 8 - 16 so that you have good DOF without blurry areas from front to back of the product. Hopefully you receive this as constructive! Here's a photo from a brochure, this is a product we make:



It's about 13" deep and 12 or 11" across. You need to play with strobes to illuminate areas that your on body bounce flash doesn't get. You can also see that the front edge and back edge are in focus. The drop shadow was necessary for the brochure.
