I'm pretty sure the next thing on my list is a great flash. So far, I have the Sony a230 w/ 18-55 kit lens, a 50mm 1.7 lens, a super cheap tripod, and a good bag. However, I'm doing a lot of indoor shooting during the Christmas season, and I'm thinking I could benefit most for a good flash I can bounce around. I've been on Adorama's website, and there are plenty of flashes, but most have no reviews, and some have 1 star reviews... I don't want to get stuck with a 1 star quality flash here, so I'm asking all of you, which flash would you recommend for under $100?
