My girlfriend just got her 40D back from Canon NJ. $180 (listed as just labor) plus tax and shipping, and they replaced the "dial assembly". Interesting that there's no parts charge. We also recently got our 16-35/2.8II back from Canon NJ - $90 (listed as just labor)+T/S, and they replaced the filter ring assembly. Maybe parts have a lifetime warranty or something, because I can't fathom why they aren't charging for them.
