I'm looking to get my first speedlite and I'm not interested in spending $200+ on a light that I only want to use occasionally. I have read a lot about why I need to skip the current 270ex... But I don't see anything like "Speedlites on a budget" when I'm looking around online. What are some other models (non canon/older) that people have been happy with in the past that someone like me would see as a good buy to have on certain occasions? How's the 380ex? etc..? Thank you for your help and advice. I have a 50D in case that matters.
