This thread has absolutely nothing to do with cost and everything to do with how much you value the item for what you spent on it. I'll start it off with my top three:
1. Crumpler Industry Disgrace neckstrap - The Canon branded one is still and cuts into your neck. It's ok for short periods or for lighter cameras but the new strap can be work many ways easily and is always comfortable. Investment - $25
2. Canon 17-55mm - This was a tough one. While I love my 100mm F2.8L IS macro, the 17-55mm can't be denied for its versatility. I use it often, especially when planning on taking pictures indoors. It can resolve so much detail that it really shows off the 50D's resolution. F2.8 and IS are just icing on the cake. Investment - $960
3. Canon 430EX II - I use to hate flash. I planned on never using flash. Then after hearing time and time again that getting a flash will improve your photography I broke down and bought one. Boy is it fun to use. Bouncing the flash can get me really sharp, noise-free and natural looking shots indoors at ISO100-200. I still need to play with it more but it has exceeded my expectations. Investment - $250
Now...it's your turn!
