Hey there all, I am shooting with a Digital Rebel EOS and I am just looking for a little help on selecting a slave flash for it. I don't really know a lot about them, and if I can get a good one for under 300 that would be great. I see a lot on Ebay, but in some cases you never know what you will get there. So the question is what kind of slave flash works good with my model? Also if anyone sees one on Ebay that you think will work for me, please let me know.
