I found this on Gadget Infinity. I know you get what you pay for, but I am on a pretty tight budget. Took me quite a few months just to save up for my D40 kit http://www.gadgetinfinity.com/product.php?productid=16535&cat=256&page=1 $50 for a flash with a sensor built in to detect the on camera flash. Has anyone had any experience with these, and does anything else similar to this exist that doesn't cost an arm and a leg? This is really intriguing to me, and if it works halfway decent, seems to be a very affordable way to start dabbling in some off camera lighting work. I've also considered some of the "Poverty Wizards" made by GI, and doing the antenna mod on them to increase the range and reliability, but even that would be overall more expensive than the flash linked above. (Not MUCH more expensive, mind you, but every penny saved helps!) Thanks!
