Can anybody recommend a good, economical brand for light stands? I have small Medal Light and larger White Lightning monolights. I have stands for all of them, but the Medal Light ones are very unstable and I don't want to use them for safety reasons. Normal use only requires an umbrella, but I may start using a softbox in the future. I shoot in my living room and I'm on a budget, but I want something dependable and long lasting. Is there anything out there that's a good balance?
