I'm looking to buy the canon 580ex flash soon. But, I am hoping to get a discount off the normal $420 retail price. I know that (hopefully) soon rebates will be out for the holidays, but any other suggestions? I'd like to get it sooner than later! :) Thanks!

I use Duracell "Rechargable Accu" batteries. They are NiMH and have 2050mAh. They work great so far in my 580EX. Here is a great article on batteries... http://www.steves-digicams.com/nimh_batteries.html
