I just want to share my happiness with you. I found something awesome at the local photostore. In the big "This-stuff-costs-$10" box I found a Jessops Flash Sync Cable for Canon EOS (transfers all the flash exposure data from the camera to the flash and vice versa)! The ordinary price is £29.99 ($52). The world is sometimes with me
It is amazing (and possibly an error) that it ended up on sale for $10. It is perfectly suitable for the digital Canon SLRs, so it isn't even unsellable at normal price.
